The DFT® Restrictor Check Valve (RCV) is a versatile, all-purpose, spring-assisted, in-line check valve for applications that require higher cracking pressures to open the check valve than those offered by other DFT® check valves. Cracking pressures are available from 2 to 40 psi. Like the Basic-Check® valve, the Restrictor Check provides reliable, low maintenance service for a wide range of fluids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, retaining ring and seat. It can be combined with pipe fittings such as couplings, drain elbows, etc. (not provided by DFT®) to form a complete check valve unit ideally suited for a broad range of applications. The RCV should not be considered a substitute for a Pressure Relief Valve.
Not recommended for use on discharge of reciprocating compressors.

Warning: Use with extra deep, bell reducer only

Standard Features:
  • 1/4" to 2 1/2" Line Size
  • Higher Cracking Pressures (2 to 40 psi)
  • 450 to 2500 CWP
  • Threaded Ends
  • Stainless Steel Construction
  • Spring-Assisted Silent Closing
  • Horizontal or Vertical Installation
  • Tight Shutoff - Lapped Disc & Seat
