Cla-Val 90-01 / 690-01

Hydraulic pressure reducing valve for water distribution networks. Reduces higher upstream pressure to a stable, lower downstream setpoint, independent of inlet pressure or flow fluctuations, within sizing limits.

Operation

Pilot-operated regulator. When downstream pressure exceeds the pilot setpoint, both the main valve and pilot close tightly to maintain control. No external power required; actuation is hydraulic via pilot system.

Applications

  • Pressure zoning in potable water networks
  • Downstream pipeline and instrumentation protection
  • Pressure stabilization under variable demand
  • Industrial water distribution systems
  • HVAC or auxiliary water circuit supply

Variants

  • 90-01: Full port configuration.
  • 690-01: Reduced port for lower flow rates or improved control in oversized pipelines.

Construction

  • Connection: Flanged
  • Standard: ANSI
  • Pressure classes: 150 lbs, 300 lbs
  • Body materials: Brass, ASTM A216 WCB, ductile iron

Selection Criteria

Sizing based on peak and minimum flow, upstream pressure, required downstream setpoint, pressure reduction ratio, flow velocity, and cavitation risk. Media compatibility and maintenance access should be considered.

FAQ

Is this a sustaining valve?
No. It regulates downstream pressure only.

Is electrical power required?
No. Operation is fully hydraulic via pilot.

Description

Cla-Val Models 90-01 and 690-01 Pressure Reducing Valves automatically reduce higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. Each 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.

Model 90-01 is the full port version, while Model 690-01 is the reduced port version of Cla-Val’s iconic Pressure Reducing Valve.
