Although they are often confused, relief valves and safety valves serve different functions. <\/p><p class=\"wp-block-paragraph\">While <strong>safety valves<\/strong> are designed to open immediately in extreme emergency situations, <strong>relief valves<\/strong> respond progressively to small pressure increases, providing more precise control and preventing sudden fluctuations in the system.<\/p><p class=\"wp-block-paragraph\">These valves are essential in industries such as chemicals, food, energy, and pharmaceuticals, where pressure control is vital for production processes to run correctly.<\/p><div class=\"wp-block-group vf-post-gallery vf-n2 is-layout-flow wp-block-group-is-layout-flow\"><figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.valfonta.com\/wp-content\/uploads\/2026\/10\/valvula-de-alivio-de-presion-regulable-3-300x300-1.webp\" alt=\"Pressure relief valve\" class=\"wp-image-293\" width=\"300\" height=\"300\" loading=\"lazy\"\/><\/figure><figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.valfonta.com\/wp-content\/uploads\/2026\/10\/valvula-de-exceso-de-presion-modelo-prv53-237x300-1.png\" alt=\"Valfonta Model PRV53 excess pressure valve\" class=\"wp-image-294\" width=\"237\" height=\"300\" loading=\"lazy\"\/><\/figure><\/div><h3 class=\"wp-block-heading\" id=\"como-funciona-una-valvula-de-alivio-de-presion\"><strong>How does a pressure relief valve work?<\/strong><\/h3><p class=\"wp-block-paragraph\">The operating principle of a pressure relief valve is simple yet highly effective. Normally, the valve remains closed as long as the system pressure stays below the defined set point. When the inlet pressure exceeds this limit, the force of the fluid overcomes the resistance of the internal spring or actuator, causing the plug to open progressively\u200b\u200b.<\/p><p class=\"wp-block-paragraph\">This movement allows part of the fluid to escape, thereby reducing the pressure in the line until normal conditions are restored. Once equilibrium is restored, the spring returns the plug to its original position and the valve closes automatically.<\/p><p class=\"wp-block-paragraph\">In Valfonta models, such as the S1 or S2 excess pressure valves and the S3 relief valves, this operation is achieved through highly sensitive self-operated systems capable of working with steam, compressed air, inert gases, or liquids, ensuring effective control over a wide range of pressures and temperatures.<\/p><h2 class=\"wp-block-heading\" id=\"factores-clave-para-elegir-una-valvula-de-alivio\"><strong>Key factors in choosing a relief valve<\/strong><\/h2><h3 class=\"wp-block-heading\" id=\"tipo-de-fluido\">Fluid type<\/h3><p class=\"wp-block-paragraph\">The first fundamental criterion is the type of fluid that will flow through the valve. Not all models are suitable for every medium.<br> Valfonta relief valves are designed to work with:<\/p><ul class=\"wp-block-list\"><li><strong>Steam<\/strong><\/li><li><strong>Compressed air<\/strong><\/li><li><strong>Inert gases<\/strong><\/li><li><strong>Industrial liquids<\/strong>\u200b\u200b\u200b.<\/li><\/ul><p class=\"wp-block-paragraph\">For example, for high-temperature steam, you will need a model that can withstand those extreme thermal conditions, such as the S3\u200b. <\/p><p class=\"wp-block-paragraph\">For corrosive fluids, it may be advisable to choose valves made of AISI 316L stainless steel\u200b\u200b.<\/p><h3 class=\"wp-block-heading\" id=\"rango-de-presion-de-trabajo\">Working pressure range<\/h3><p class=\"wp-block-paragraph\">Each valve has a specific pressure range within which it can operate safely and effectively. It is essential to know both the <strong>normal working pressure<\/strong> and the <strong>pressure peaks<\/strong> that may occur.<\/p><p class=\"wp-block-paragraph\">Examples of regulation ranges in Valfonta products:<\/p><ul class=\"wp-block-list\"><li><strong>Model S1:<\/strong> from 0.1 to 15 barg\u200b.<\/li><li><strong>Model S2:<\/strong> from 0.02 to 10 barg\u200b.<br>\n<strong>Model PRV53:<\/strong> from 0.5 to 10 barg\u200b.<\/li><li><strong>Model PRV55:<\/strong> from 0.01 to 8 barg\u200b.<\/li><\/ul><p class=\"wp-block-paragraph\">Selecting a model that operates within the right range extends the service life of the valve and improves the safety of the entire system.<\/p><div class=\"wp-block-group vf-post-gallery vf-n2 is-layout-flow wp-block-group-is-layout-flow\"><figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.valfonta.com\/wp-content\/uploads\/2026\/10\/valvula-de-alivio-de-presion-regulable-2-300x300-1.webp\" alt=\"Pressure relief valve\" class=\"wp-image-292\" width=\"300\" height=\"300\" loading=\"lazy\"\/><\/figure><figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.valfonta.com\/wp-content\/uploads\/2026\/10\/Valvula-industrial-M2-300x300-1.jpg\" alt=\"Pressure relief valve\" class=\"wp-image-295\" width=\"300\" height=\"300\" loading=\"lazy\"\/><\/figure><\/div><h3 class=\"wp-block-heading\" id=\"temperatura-de-operacion\">Operating temperature<\/h3><p class=\"wp-block-paragraph\">Fluid temperature is another critical parameter.<br> Each diaphragm and gasket material has a safe operating temperature limit:<\/p><ul class=\"wp-block-list\"><li><strong>NBR:<\/strong> -20\u00baC to 80\u00baC<\/li><li><strong>EPDM:<\/strong> -40\u00baC to 125\u00baC<\/li><li><strong>PTFE:<\/strong> up to 220\u00baC\u200b\u200b.<\/li><\/ul><p class=\"wp-block-paragraph\">In steam or very hot fluid applications, you must make sure that both the body and the internal components of the valve can withstand the expected temperature.<\/p><h3 class=\"wp-block-heading\" id=\"materiales-de-construccion\">Construction materials<\/h3><p class=\"wp-block-paragraph\">The materials of the body and internal components will determine the valve\u2019s resistance to corrosion, pressure, and temperature.<\/p><p class=\"wp-block-paragraph\">At Valfonta we use materials such as:<\/p><ul class=\"wp-block-list\"><li><strong>RG10 bronze<\/strong><strong><br>\n<\/strong><strong>A216 WCB carbon steel<\/strong><\/li><li><strong>A351 CF3M stainless steel<\/strong>\u200b\u200b\u200b.<\/li><li>Duplex or super duplex (on request)<\/li><\/ul><p class=\"wp-block-paragraph\">For demanding environments or aggressive fluids, we recommend choosing versions made entirely of stainless steel.<\/p><h3 class=\"wp-block-heading\" id=\"conexiones-y-normativas\">Connections and regulations<\/h3><p class=\"wp-block-paragraph\">Another aspect to consider is the valve\u2019s <strong>connections<\/strong>:<\/p><ul class=\"wp-block-list\"><li><strong>DIN PN16\u2013PN40 flanges<\/strong><\/li><li><strong>ANSI 150\/300 flanges<\/strong><\/li><li><strong>BSP or NPT threads<\/strong>\u200b\u200b.<\/li><\/ul><p class=\"wp-block-paragraph\">It is also essential that the valves comply with current European regulations such as the <strong>Pressure Equipment Directive PED 2014\/68\/EU<\/strong> and, where applicable, <strong>ATEX<\/strong> certification for explosive atmospheres.<\/p><figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.valfonta.com\/wp-content\/uploads\/2026\/10\/Valvula-de-exceso-de-presion-PRV54-300x300-1.jpg\" alt=\"Pressure relief valve\" class=\"wp-image-296\" width=\"300\" height=\"300\" loading=\"lazy\"\/><\/figure><h2 class=\"wp-block-heading\" id=\"tipos-de-valvulas-de-alivio-de-presion-valfonta\"><strong> Types of Valfonta pressure relief valves<\/strong><\/h2><p class=\"wp-block-paragraph\">At Valfonta we offer a complete range of pressure relief valves to meet the needs of different industrial sectors.

Valfonta offers the S1, S2, S3, PRV53, PRV54, and PRV55 models; the S3 handles fluids up to 220 \u00b0C and set pressures up to 20 barg.

This can lead to serious damage to pipes, vessels, pumps, or other equipment, as well as posing a risk to people\u2019s safety. A relief valve acts as passive insurance: it remains closed under normal conditions and is activated only when necessary, preventing costly or even fatal accidents.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between a relief valve and a safety valve?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Although both devices protect against overpressure, they have important differences: Relief valve: opens progressively in response to a controlled pressure increase. Ideal for processes that require finer regulation. Safety valve: designed to open quickly and fully in extreme overpressure situations, as an emergency measure. In many cases both types must be installed together to ensure comprehensive protection.\"}},{\"@type\":\"Question\",\"name\":\"How do you adjust the opening pressure of a relief valve?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The opening pressure is normally adjusted using an adjusting screw or nut located on the upper actuator of the valve\u200b\u200b. Turning it clockwise increases the set pressure; turning it counterclockwise reduces it. It is essential to carry out this operation carefully and, if possible, following the specific instructions for each model.\"}},{\"@type\":\"Question\",\"name\":\"How often should a relief valve be inspected or serviced?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Although Valfonta pressure relief valves are low-maintenance, a preventive inspection at least once a year is recommended, especially in critical systems or under intensive operating conditions. The inspection should check: condition of the plug and seat; diaphragms and gaskets; correct operation of the adjusting mechanism; possible leaks or dirt buildup. Proper maintenance ensures correct operation and extends the service life of the valve.\"}}]}]}]","footnotes":"","_vg_translation_of":"491","_vg_lang":"en","_vg_wpml_state":"{\"lang\":\"en\",\"trid\":\"678\",\"src\":\"es\"}"},"categories":[37],"tags":[],"class_list":["post-717","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-relief-and-safety"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/717","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/comments?post=717"}],"version-history":[{"count":4,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/717\/revisions"}],"predecessor-version":[{"id":10319,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/717\/revisions\/10319"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/media\/238"}],"wp:attachment":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/media?parent=717"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/categories?post=717"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/tags?post=717"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
