Features

  • Body Material: Carbon steel or stainless steel.
  • Trim Material: Choice of four combinations of ma te rials, including 316L SST wetted.
  • Setpoint Pressure Range: Multiple springs covering 2.0 - 16.0" W.C. (50 - 400mm H2 O).
  • Accurate Regulation: Optimum internals design to ensure rapid response to sudden load changes.
  • Multiple Configurations: Valve is factory assembled in four standard positions. Actuator section can be rotated 360° around the valve’s throat.
  • Valve Seat Design: One-piece, molded, resilient seat self-locks, self-aligns, and is easily field maintained. Design minimizes pressure build above setpoint at lockup (no flow) conditions. Buna-N, fluorocarbon elastomer, silicone or TFE seat material. Loading ring allows field adjustment of “boost effect”.
