Hydraulic Pump Control & Back Pressure Valve - 60-32 & 660-32 | Cla-Val

Cla-Val 60-32 / 660-32 – Pump Control Valve with Back Pressure

The Cla-Val 60-32 / 660-32 is a pilot-operated pump discharge control valve designed for booster pump applications. It integrates pump start/stop sequencing with adjustable back pressure regulation during operation.

Operation

When the pump is offline, the valve remains closed due to system pressure. On pump start, the CS3M solenoid is energized, causing the valve to open gradually, allowing controlled flow and pressure increase up to the set back pressure. During shutdown, the valve closes in a controlled manner; the X105LCW limit switch stops the pump after full closure.

Materials and Sealing

Body: ductile iron ASTM A536, cast steel ASTM A216 WCB, or bronze UNS 87850. Disc and diaphragm: Buna-N. Stem and spring: stainless steel. Pilot system available in low-lead bronze, stainless steel, or Monel. Sealing options depend on media compatibility and process requirements.

Applications

• Booster pump stations with multiple pumps

• Industrial water distribution systems
• Installations requiring lift-type non-return function
• Systems with pump/valve electrical interlock

Selection Considerations

Selection is based on flow rate, allowable pressure loss, pressure class, back pressure range, trim material, and solenoid voltage. For power failure protection, use surge anticipator 52-03 / 652-03. Ensure compatibility with process media and required certifications.
