The M1, M2, and PRV45 work with a diaphragm; the M2F and PRV44, with a bellows; the PRV20 and PRV30 are piston-balanced; and the VD uses a piston guided at three points. Most work with liquids, inert gases, and steam, with different ranges: the M1 regulates from 0.1 to 15 barg.<\/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=\"#contamos-con-un-amplio-rango-de-valvulas-reductoras-de-presi\">We offer a wide range of pressure reducing valves for industrial systems<\/a><\/p><ol class=\"wp-block-list\"><li><a href=\"#valvula-reductora-modelo-m1\">M1 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-m2\">M2 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-m2-fuelle\">M2+Bellows reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-prv20\">PRV20 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-prv30\">PRV30 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-prv44\">PRV44 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-prv45\">PRV45 reducing valve<\/a><\/li><li><a href=\"#valvula-reductora-modelo-vd\">VD reducing valve<\/a><\/li><\/ol><\/div><\/div><\/details><h2 class=\"wp-block-heading\" id=\"contamos-con-un-amplio-rango-de-valvulas-reductoras-de-presi\"><strong>We offer a wide range of pressure reducing valves for industrial systems<\/strong><\/h2><p class=\"wp-block-paragraph\">At Valfonta, we offer a <strong>wide range of industrial pressure reducing valves<\/strong>, designed to ensure safety, efficiency, and stability in processes where pressure control is a critical factor.
