Hydraulic Booster Pump Control Valve with High-Capacity Solenoid - 60-BY & 660-BY | Cla-Val

Cla-Val 60-BY / 660-BY – Booster Pump Control Valve

The Cla-Val 60-BY / 660-BY is a pilot-operated valve designed for installation on the discharge side of booster pumps. It utilizes a high-capacity CSM11-HC solenoid pilot for controlled opening/closing and to limit hydraulic transients during pump start and stop sequences.

Operating Sequence

Pump startup occurs with the valve in the closed position. Upon energizing the solenoid, the valve opens gradually, allowing line pressure to increase in a controlled manner. During shutdown, the solenoid de-energizes, the valve closes at a controlled rate, and the X105LCW limit switch releases the pump starter only after the valve is fully closed.

Technical Data

• Main valve: Hycheck 100-04, integrated lift-type check feature
• Sizes: DN150–DN400 / 6"–16"
• Body style: globe or angle pattern
• Connection: ANSI flanged
• Pressure classes: ANSI 150 / 300
• Body materials: ASTM A536 ductile iron, ASTM A216 WCB cast steel, or bronze UNS 87850
• Sealing: Buna-N disc, reinforced Buna-N diaphragm
• Stem/spring: stainless steel
• Water temperature: up to 82 °C
• Solenoid operating pressure: up to 300 psi

Applications

Suitable for water supply pump stations, multiple booster pump systems, industrial water networks, and lines requiring hydraulic pump control with electrical interlock. For installations with risk of power failure, integration with surge anticipator valves (52-03 / 652-03) is recommended.

Selection Criteria

Valve selection is based on pump flow rate, allowable pressure loss, pressure class, trim material, and solenoid voltage. For applications with pressures below 10 psi, engineering review is required.
