Cla-Val 136-01 Solenoid Control Valve

A hydraulic on-off valve operated by an electrical signal

The Cla-Val 136-01 is an on-off control valve that opens or closes when its solenoid pilot receives an electrical signal. It consists of a Hytrol 100-01 main valve and a three-way CS3 solenoid valve that alternately applies pressure to, or relieves pressure from, the diaphragm chamber of the main valve. The valve is furnished normally open (solenoid de-energized to open) or normally closed (energized to open).

Cla-Val lists fast-acting solenoid control, reliable drip-tight shut-off and easy installation and maintenance. A check feature is optional.

Technical specifications

Electrical and process limits

The solenoid body is brass to ASTM B283 with Buna-N rubber parts. The standard enclosure is a general purpose watertight NEMA 1, 2, 3, 3S, 4 or 4X; NEMA 6, 6P, 7 or 9 explosion-proof enclosures are listed as available. Voltages are 110 and 220 V at 50 Hz, 24, 120, 240 and 480 V at 60 Hz AC, and 6, 12, 24, 120 and 240 V DC, with others at additional cost. The AC coil draws 30 VA inrush and 16 VA holding, 6 W, and the DC coil 10.6 W. A manual operator is an option.

The maximum operating pressure differential is 200 psi unless otherwise specified, and a flowing pressure differential of at least 5 psi is required. The solenoid fluids are air, water and light oils, and the temperature limit is water to 180 °F.

Applications and options

Industrial uses named by Cla-Val are accurate control of process water for batching, mixing, washing and blending. For tank filling, a float switch or an electrode probe can send the electrical signal that opens or closes the valve, which turns the 136-01 into a simple liquid level control.

Suggested maximum flow is 55 gpm at 1 in, 125 gpm at 1-1/2 in, 210 gpm at 2 in, 460 gpm at 3 in and 800 gpm at 4 in. Options include an X46A strainer, CK2 isolation valves, CNA closing and opening speed controls, a check valve with isolation valve, an X141 gauge, an X101 position indicator and an X43 Y-strainer or X43H stainless steel strainer.

How the Cla-Val 136-01 works

The main valve is a Hytrol 100-01, a hydraulically operated diaphragm valve. Line pressure acts on a diaphragm chamber above the valve seat. When the pressure is applied to the chamber, the diaphragm pushes the valve closed. When the pressure is relieved, the line pressure lifts the diaphragm and the valve opens. The CS3 three-way solenoid valve decides which of the two happens. When the solenoid is switched, it either feeds the chamber or vents it. The valve is therefore opened and closed by an electric signal, using the pressure of the line. A normally open version opens when the solenoid is de-energized, and a normally closed version opens when it is energized.

Where the 136-01 is used

• Remote on-off control of water lines
• Tank filling and level control with a float or probe switch
• Irrigation and process water lines
• Cooling water and fire protection supply lines
• Automatic isolation by a control system or timer

Selection checklist for the 136-01

• Size from 1/2 to 4 in and the end connection, threaded, flanged or grooved
• Body material, ductile iron, cast steel or bronze
• Pressure class, 150 or 300, and the system pressure
• Normally open or normally closed operation
• Solenoid voltage and frequency, and the coil power
• Enclosure, NEMA 1 to 4X or an explosion-proof NEMA 7 or 9
• Flow, against the suggested maximum for the size
• Water temperature up to 180 degrees F (82 degrees C)

Installation, commissioning and maintenance notes

Flush the line before installing the valve so that debris does not reach the pilot system. Fit the valve with the flow in the direction marked on the body, and leave room around it for service. Wire the solenoid to the correct voltage and check the supply. A strainer upstream protects the pilot parts. Test the valve by cycling it a few times, and listen for a clean, quick action. Inspect the pilot and the diaphragm at overhauls.

136-01 differential pressure

The maximum operating differential is 200 psi unless specified otherwise. A flowing differential of at least 5 psi is needed for the valve to operate.

136-01 solenoid

The CS3 solenoid has a brass body and Buna-N rubber parts. The AC coil takes 6 W, with 30 VA inrush and 16 VA holding, and the DC coil takes 10.6 W.
