It protects equipment that cannot withstand the line pressure and keeps the process running under the same conditions at all times.<\/p><p class=\"wp-block-paragraph\">Valfonta reducing valves are <strong>self-operated<\/strong>: a spring opposes the outlet pressure, and that balance moves the plug, with no air, electricity, or control system. Compressing the spring raises the outlet pressure.<\/p><p class=\"wp-block-paragraph\">They are installed in the line, ahead of the consumer they protect, with shutoff valves, a strainer, inlet and outlet pressure gauges, and a safety valve downstream.

Valfonta valves are self-operated: they run on the energy of the fluid itself, with no air or electricity.<\/p><\/div><\/details><details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Which reducing valve do I need for steam?<\/summary><div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\"><p class=\"wp-block-paragraph\">For steam, the suitable models are the PRV44 (up to 210 \u00b0C), the PRV45 (up to 150 \u00b0C), the VD (up to 200 \u00b0C), the M1 (up to 220 \u00b0C), the M2 (up to 180 \u00b0C), and the M2F (up to 200 \u00b0C without a condensate pot). The PRV20 and the PRV30 are not suitable for steam.<\/p><\/div><\/details><details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>What is the lowest outlet pressure that can be regulated?<\/summary><div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\"><p class=\"wp-block-paragraph\">The PRV45 regulates from 0.01 barg (10 mbar) and the M2 from 0.02 barg. For higher outlet pressures, the PRV20 reaches 20 barg.<\/p><\/div><\/details><details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Do they need auxiliary power or a control system?<\/summary><div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\"><p class=\"wp-block-paragraph\">No. The adjusting spring and the outlet pressure balance the plug. If you need to control the pressure from a control system, see the <a href=\"https:\/\/www.valfonta.com\/en\/product\/c1-gas-control-valve\/\">C1 control valve with pneumatic actuator<\/a>.<\/p><\/div><\/details><details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Does a reducing valve replace a safety valve?<\/summary><div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\"><p class=\"wp-block-paragraph\">No. The reducing valve regulates the outlet pressure but does not protect against overpressure: if the installation requires it, also install a <a href=\"https:\/\/www.valfonta.com\/en\/safety-valves\/\">safety valve<\/a> downstream.<\/p><\/div><\/details><details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>What information does Valfonta need to prepare a quote?<\/summary><div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\"><p class=\"wp-block-paragraph\">The fluid and its temperature, the inlet pressure, the desired outlet pressure, the maximum and minimum flow rate, and the connection type.
