Pressure Reducing Valves
Self Actuating [ Mechanical type ] - PRV-100 SERIES

Product description:

Self Actuating, Internally Sensed Pilot & Piston operated, Direct Spring & Diaphragm Actuated, Top & Bottom Guided Pressure Reducing Valve with screwed / Flanged End connection.

Design:
  • PRV-100 Series type PRV consisting of two Valves - an internal Pilot & Main Valve
  • Highly Sensitive Pilot
  • This Valve Operates on Spring & Diaphragm Balance Principal
  • Very High flow Rate due to full lift of main Valve and Body design
  • Extremely compact & Light weight design
  • The Internal Pilot design eliminates external Piping Sense
Features:
  • Compact & Versatile design for accurate regulation with widest possible range of flow.
  • High flow rate with greater accuracy due to full lift design.
  • Stallited trims for high pressure & temperature.
  • A positive tight shut off by accurate guiding of pilot & main valve assembly.
  • Constant Outlet pressure is accurately maintain without unaffecting by changes in inlet pressure or flow rate.
  • Stainless Steel Diaphragm & Harden internal parts provide high performance over long period & trouble free service life.
  • Non metallic trims to give dead tight shut off on air & non corrosive gas application

Note : *We Recommend to Provide External Balance Pipe when the Reduced Pressure is Below 55% of the Inlet Pressure

Application:

Steam-Con PRV-100 Series of Internally Pilot & Piston Operated Pressure Reducing Valve Provide Extremely accurate levels of Pressure Regulation for Steam, air and Industrial gas application. This is accomplished with a highly sensitive pilot which continuously monitors both inlet & outlet Pressure simultaneously. The result is a constant pressure irrespective of erratic inlet pressure of system demand.
