Electronic Solenoid Control Valve - 136-03 & 636-03 | Cla-Val

Cla-Val 136-03 / 636-03 Electromagnetic On-Off Valve

The Cla-Val 136-03 / 636-03 is a hydraulically actuated control valve for water, featuring a Hytrol main valve, a three-way solenoid pilot, and a high-capacity pilot valve. It operates as an on-off valve: the main valve fully opens or closes in response to an electrical signal at the solenoid pilot.

Operating Principle

The solenoid actuates the three-way pilot valve, which alternates pressure in the diaphragm chamber of the main valve. Two logic options are available:

• Normally open: de-energize solenoid to open
• Normally closed: energize solenoid to open

Technical Data

• Operation: full open / tight shut-off
• Connection: flanged
• Standard: ANSI
• Pressure class: 150 lbs or 300 lbs
• Body materials: brass, ASTM A216 WCB, ductile iron
• Suitable media: potable water or industrial process water

Applications

• Remote open/close via PLC or SCADA
• Tank filling and batching
• Flow shut-off in water supply or irrigation lines
• Level automation with electrical command
• Applications requiring higher pilot flow than standard solenoid assemblies

Difference from 136-01

The 136-03 / 636-03 includes a high-capacity three-way pilot valve in addition to the solenoid. This enables faster hydraulic response of the main valve, especially for larger DN or where open/close time must be functionally controlled.

FAQ

Is this a modulating valve?
No. It is an on-off valve, not a proportional control valve.

What data is required for selection?
DN, inlet/outlet pressure, flow rate, solenoid voltage, fail position, and pressure class.
