Hydraulic Pressure Control Valves - 139-10 & 639-10 Programmable Timer Control Valve | Cla-Val

Cla-Val 139-10 / 639-10 with Timer Control

Hydraulic on-off control valve for water distribution networks, featuring scheduled open/close operation. Utilizes the CTC-33 electronic timer, suitable for remote installations without SCADA integration.

Operation

Valve actuates according to a weekly schedule. The CTC-33 supports up to 4 open/close cycles per day, powered by a 9V lithium battery (PP3). The actuator enclosure is rated IP68 for submersible operation. Maximum working pressure: 16 bar. Temperature range: -10°C to +80°C. Designed for potable water and compatible process fluids.

Typical Applications

• Zonal pressure management in municipal water supply networks.
• Leakage reduction during low demand periods.
• Scheduled pipeline flushing for water quality control.
• Irrigation and industrial water systems requiring periodic operation.
• Sites lacking automation cabling or telemetry infrastructure.

Construction and Options

Supplied with Hytrol 100-01 main valve, full port, available in globe or angle pattern. Connections: threaded, flanged, or grooved, depending on size. Body materials: ductile iron ASTM A536, cast steel ASTM A216 WCB, or bronze. Flange classes: ANSI 150 and 300.

Optional Accessories

• Pilot line filter X43 or X46A
• Isolation valves CK2
• Pressure gauge X141
• Position indicator X101

Selection Criteria

Selection is based on diameter, flow rate, network pressure, connection type, trim material, and required timing program. For low flow rates, verify compatibility with the valve’s operational range to avoid leakage or instability.

FAQ

Is this a pressure regulating valve?

This is an on-off valve with timer control. It can be combined with pressure, flow, or level pilots if required.

Compatible media?

Water.

Is external power required?

No. The CTC-33 operates on lithium battery power.
