A pressure reducing valve is used for controlling

The Samson make Type 41-23 self-operated universal pressure reducing regulator is a standard size regulator (1/2" - 4") designed to work in all general industrial applications. A pressure reducing valve is used for controlling the downstream pressure (p2) to an adjusted set point. The design of a pressure reducing regulator valve is to close when the downstream pressure rises above a set value.

These valves are self-operated in that the downstream pressure being controlled is tapped downstream of the Pressure Reducing Valve and transmitted via a control line to the operating diaphragm of the Type 41-23 where it is converted into a positioning force.

    Special features of Pressure Reducing Valve:
  • Low-maintenance proportional regulators requiring no auxiliary energy
  • Frictionless plug stem seal with stainless steel bellows
  • Control line kit available for tapping the pressure directly at the valve body
  • Wide set point range and convenient set point adjustment using a nut
  • Exchangeable set point springs and actuator
  • Spring-loaded, single-seated Pressure Reducing Valve with upstream and down stream pressure balancing by a stainless steel bellows
  • Soft-seated plug for high shut-off requirements
  • Standard low-noise plug
  • Special version with flow dividerSt I or St III (NPS 2½ to 4/DN 65 to 100) for further noise level reduction
  • All wetted parts free of non-ferrous metal

    Application of Pressure Reducing Valve:
  • Pressure regulators for set points from 0.75 to 400 psi (0.05 to 28 bar)
  • Valves in NPS ½ to 4 (DN 15 to 100)
  • Pressure rating Class 125 to 300 (PN 16 to 40)
  • Suitable for water,gases, and vapors up to 660 °F (350 °C)
