Cla-Val 139-10 / 639-10

Hydraulically actuated, diaphragm-type control valve with pilot control, designed for electronic operation in water distribution networks. Solenoid pilots are actuated by electrical signals from the VC-22D controller, charging or venting the cover chamber to open or close the main valve.

Process Operation

Used where remote control via PLC, SCADA, or field controller is required. The VC-22D compares process signals to set points and adjusts valve position through the pilot circuit.

Typical functions:

  • pressure reducing
  • pressure sustaining
  • flow control
  • level control
  • blending of water with different quality for regulatory compliance

139-10 vs 639-10

The 139-10 uses a full-port 100-01 main valve.
The 639-10 is specified for reduced-port sizing, typically for lower flow rates relative to pipeline diameter.

Construction

  • Connection: flanged
  • Standard: ANSI
  • Pressure class: 150 or 300 lbs
  • Body materials: ductile iron, ASTM A216 WCB, bronze
  • Available accessories: X46A strainer, CK2 isolation valve, flow controls, check feature, X117 position transmitter, X141 pressure gauge

Selection Criteria

Selection should be based on flow rate, differential pressure, required fail position, water quality, response time, and pilot circuit maintenance accessibility.

FAQ

Is this an electric valve?

Main actuation is hydraulic. Electrical signal only actuates the pilots.

Where is it applied?

Potable water networks, industrial water, blending, pressure zones, and remote control points.

Description

Cla-Val Series 131 and 631 Electronic Control Valves are designed specifically for applications where remote control of valve function is preferred. They are hydraulically operated, pilot controlled, diaphragm valves. The solenoid pilot controls are actuated by electrical signals from the VC-22D Electronic Valve Controller. The solenoid pilots either add or relieve line pressure from the cover chamber of the valve, causing it to open or close as directed by the electronic controller.

Use this valve for applications where water containing unacceptable levels of chemicals is blended with clean water to achieve compliance with State and Federal regulatory requirements.
