To reduce pressure, Valfonta recommends the M1, M2, PRV20, PRV44, and VD models; for relief, the S1, S2, S3, PRV53, PRV54, and PRV55; and for control, the C1. The choice depends on the fluid, the operating pressure and temperature, regulatory requirements, connections, and maintenance.<\/p><\/aside><details class=\"wp-block-details vf-post-toc-m is-layout-flow wp-block-details-is-layout-flow\"><summary>Article contents<\/summary><ol class=\"wp-block-list\"><li><a href=\"#empecemos-nuestra-guia-sobre-valvulas-industriales\">Let\u2019s begin our guide to industrial valves<\/a><\/li><li><a href=\"#que-es-una-valvula-industrial-y-que-funciones-puede-cumplir\">What is an industrial valve and what functions can it perform?<\/a><\/li><li><a href=\"#valvulas-reductoras-de-presion\">Pressure reducing valves<\/a><\/li><li><a href=\"#valvulas-de-alivio-de-presion\">Pressure relief valves<\/a><\/li><li><a href=\"#tabla-comparativa-de-tipos-de-valvulas-industriales\">Comparison table of industrial valve types<\/a><\/li><\/ol><\/details><h2 class=\"wp-block-heading\" id=\"empecemos-nuestra-guia-sobre-valvulas-industriales\">Let\u2019s begin our guide to industrial valves<\/h2><p class=\"wp-block-paragraph\">Industrial valves are essential components in any system that involves conveying, regulating, or containing pressurized fluids. <\/p><p class=\"wp-block-paragraph\">In this technical guide, we explore the main <strong>types of valves used in industry<\/strong>\u2014pressure reducing valves, relief valves, and control valves\u2014explaining their functions, characteristics, and most common applications.<br>\n<\/p><p class=\"wp-block-paragraph\">We will also detail the models developed by Valfonta, a <a href=\"\/en\/company\/\"><strong>manufacturer with more than 50 years of experience<\/strong><\/a>, and its recommendations for each type of installation.<br>\n<\/p><p class=\"wp-block-paragraph\">This guide <strong>takes an informative and practical approach,<\/strong> intended for engineers, maintenance managers, plant managers, and process technicians looking for a clear and useful reference for <strong>industrial valve selection.<\/strong><\/p><h2 class=\"wp-block-heading\" id=\"que-es-una-valvula-industrial-y-que-funciones-puede-cumplir\"><strong>What is an industrial valve and what functions can it perform?<\/strong><\/h2><p class=\"wp-block-paragraph\"><strong>An industrial valve is a mechanical device designed to control the passage of a fluid (liquid, gas, or steam) through a piping system.

Their main function is to <strong>protect the installation against occasional overpressures<\/strong> that could damage components or compromise system safety.<\/p><p class=\"wp-block-paragraph\">Unlike reducing valves, they <strong>do not act continuously<\/strong>; instead, they remain closed until the inlet pressure reaches the defined threshold.<\/p><h3 class=\"wp-block-heading\" id=\"como-funciona-una-valvula-de-alivio\"><strong>How does a relief valve work?<\/strong><\/h3><p class=\"wp-block-paragraph\">When the upstream pressure exceeds the set point, the valve opens proportionally and releases fluid until the pressure is back within the acceptable range.<br> Once equilibrium is restored, the valve closes automatically thanks to the action of the adjusting springs.<\/p><p class=\"wp-block-paragraph\">These valves <strong>should not be confused with safety valves<\/strong>, which usually open more abruptly and are intended for emergency
