You also need to evaluate the allowable leakage rate, the pressure drop, the piping system, and the balance between durability and cost. It is important to know the valve types (gate, ball, butterfly, and globe) and the European regulations, which govern equipment with a maximum allowable pressure above 0.5 barg and distinguish hazardous fluids (group 1) from all others (group 2).<\/p><\/aside><details class=\"wp-block-details vf-post-toc-m is-layout-flow wp-block-details-is-layout-flow\"><summary>Article contents<\/summary><div class=\"wp-block-group vf-t-ol is-layout-flow wp-block-group-is-layout-flow\"><div class=\"wp-block-group vf-t-li is-layout-flow wp-block-group-is-layout-flow\"><p class=\"vf-envolt wp-block-paragraph\"><a href=\"#pasos-para-disenar-una-valvula-de-presion\">Steps for designing a pressure valve<\/a><\/p><ol class=\"wp-block-list\"><li><a href=\"#seleccion-del-material-adecuado\">Selecting the Right Material<\/a><\/li><li><a href=\"#presion-y-limites-de-temperatura\">Pressure and Temperature Limits<\/a><\/li><li><a href=\"#dimensiones-y-capacidad-de-flujo\">Dimensions and Flow Capacity<\/a><\/li><li><a href=\"#rangos-de-temperatura\">Temperature Ranges<\/a><\/li><li><a href=\"#evaluacion-del-caudal-de-fuga\">Leakage Rate Evaluation<\/a><\/li><li><a href=\"#analisis-de-perdida-de-presion\">Pressure Drop Analysis<\/a><\/li><li><a href=\"#conocimiento-del-sistema-de-canerias\">Knowledge of the Piping System<\/a><\/li><li><a href=\"#durabilidad-y-coste\">Durability and Cost<\/a><\/li><\/ol><\/div><div class=\"wp-block-group vf-t-li is-layout-flow wp-block-group-is-layout-flow\"><p class=\"vf-envolt wp-block-paragraph\"><a href=\"#conceptos-a-tener-en-cuenta-a-la-hora-de-disenar-una-valvula\">Concepts to keep in mind when designing a pressure valve<\/a><\/p><ol class=\"wp-block-list\"><li><a href=\"#normativa-europea-para-disenar-valvulas-de-presion\">European regulations for designing pressure valves<\/a><\/li><li><a href=\"#para-cualquier-duda-o-aclaracion-contacte-con-nuestro-depart\">For any questions or clarifications, contact our sales department<\/a><\/li><\/ol><\/div><\/div><\/details><p class=\"wp-block-paragraph\">At Valfonta, <a href=\"https:\/\/www.valfonta.com\/en\/pressure-reducing-valves\/\"><strong>manufacturing pressure reducing valves<\/strong> <\/a>is a specialty in which we have years of accumulated experience, allowing us to guarantee the superior quality of our products.

To do this, it is essential to know all the existing valve types:<\/p><div class=\"wp-block-group vf-t-ul is-layout-flow wp-block-group-is-layout-flow\"><div class=\"wp-block-group vf-t-li is-layout-flow wp-block-group-is-layout-flow\"><p class=\"vf-envolt wp-block-paragraph\"><i><\/i><\/p><p class=\"wp-block-paragraph\"><strong>Gate valve<\/strong>: used to shut off or open the passage of a fluid, usually a liquid. Their bidirectional design allows them to be installed in either direction. It is essential that these valves be fully open or fully closed, since a failure of the gate can destroy the valve. They are in turn classified into three types, according to the wedge or disc they require: solid, flexible, and resilient.<\/p><\/div><div class=\"wp-block-group vf-t-li is-layout-flow wp-block-group-is-layout-flow\"><p class=\"vf-envolt wp-block-paragraph\"><i><\/i><\/p><p class=\"wp-block-paragraph\"><strong>Ball valve:<\/strong> these valves are also bidirectional and are used in industries with smaller sizes. The valves have a double ring, placed one at each end of the ball, providing greater safety. They are in turn classified as floating ball and trunnion-mounted ball (Trunnion), depending on the required applications.<\/p><\/div><div class=\"wp-block-group vf-t-li is-layout-flow wp-block-group-is-layout-flow\"><p class=\"vf-envolt wp-block-paragraph\"><i><\/i><\/p><p class=\"wp-block-paragraph\"><strong>Butterfly valves:<\/strong> these are the most widely used due to their versatility, and they work as an on\/off valve.

Accordingly, we will cover everything related to the European regulations.\u00a0<\/p><p class=\"wp-block-paragraph\">The Pressure Equipment Directive currently in force is <strong>2014\/68\/EU<\/strong>, which replaced 97\/23\/EC and has applied since July 19, 2016 (in Spain, Royal Decree 709\/2015). It sets out the minimum requirements for the design, manufacture, and conformity assessment of all equipment subject to a maximum allowable pressure PS above 0.5 barg 1.<\/p><p class=\"wp-block-paragraph\">On the other hand, it is essential to know what type of medium will pass through the valve (steam, liquid, or gas). It should also be noted that these media have been classified into two clearly distinct fluid groups. Group 1 covers hazardous fluids such as explosive, toxic, or oxidizing fluids. Group 2 includes all other, less harmful fluids.\u00a0<\/p><h3 class=\"wp-block-heading\" id=\"para-cualquier-duda-o-aclaracion-contacte-con-nuestro-depart\"><strong>For any questions or clarifications, contact our sales department<\/strong><\/h3><p class=\"wp-block-paragraph\">If you have questions or need further clarification, our sales team is always available to provide the assistance you need.<\/p><p class=\"wp-block-paragraph\">In engineering and industrial manufacturing, a precise understanding of technical terms and specifications is crucial.

You also need to evaluate the allowable leakage rate, the pressure drop, the piping system, and the balance between durability and cost. It is important to know the valve types (gate, ball, butterfly, and globe) and the European regulations, which govern equipment with a maximum allowable pressure above 0.5 barg and distinguish hazardous fluids (group 1) from all others (group 2).\"}]}]","footnotes":"","_vg_translation_of":"468","_vg_lang":"en","_vg_wpml_state":"{\"lang\":\"en\",\"trid\":\"632\",\"src\":\"es\"}"},"categories":[38],"tags":[],"class_list":["post-677","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-control-and-design"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/677","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=677"}],"version-history":[{"count":3,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/677\/revisions"}],"predecessor-version":[{"id":10390,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/posts\/677\/revisions\/10390"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/media\/248"}],"wp:attachment":[{"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/media?parent=677"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/categories?post=677"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.valfonta.com\/en\/wp-json\/wp\/v2\/tags?post=677"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
