Pressure Reducing Valve
DN25-DN900
Model 90-01/690-01

MODEL
  • 90-01/690-01
  VALVE DESCRIPTION
  • Sensitive and Accurate Pressure Control
  • Easy Adjustment and Maintenance
  • Tamper Resistant
  • Optional Check Feature
  • Fully Supported Frictionless Diaphragm

The Cla-Val Model 90-01/690-01 Pressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. This valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.

If a check feature is added, and a pressure reversal occurs, the downstream pressure is admitted in the main valve cover chamber, closing the valve to prevent return flow.
