Altitude and Solenoid Shut-Off Valve

with Return Flow Feature

Typical Applications

Used on reservoirs where water is supplied and withdrawn through the Altitude

Valve. Valve closes at the desired high water level controlled remotely via SCADA

system signal to solenoid or automatically with preset level control (usually set

higher). Also, valve automatically opens for return flow when the pressure at the

valve inlet lowers below the reservoir head pressure. For more information see data

sheet E-CDS6A.

*Note: The reservoir pressure sensing line should be

⁄4” minimum I.D. installed with a

2° slope from valve to reservoir to avoid air pockets.

Note: We recommend protecting tubing and valve from freezing temperatures.

The Cla-Val Model 210-27/610-27 Altitude Valve controls the high

water level in reservoirs with out the need for floats or other devices.

It is a non-throttling valve that remains fully open until the solenoid is

activated or the shut-off point of the hydraulic pilot control is reached.

The valve closes at high water level and opens for return flow when

the pressure at the valve inlet is less than reservoir pressure.

This valve is hydraulically-operated and pilot-controlled. The level pilot

control operates on the differential in forces between a spring load and

reservoir head level. When force of the spring is overcome by the

force of reservoir head, the pilot shifts and closes main valve. Desired

high water level is set by adjusting the spring force. The pilot control

measures the reservoir head through a customer supplied separate

sensing line* connected directly to the reservoir. A three-way solenoid

control and a high-capacity three-way pilot control valve provide

override shut-off of valve from a remote location, such as a SCADA

control system. It is furnished either normally open (de-energize

solenoid to open) or normally closed (energize solenoid to open).

The valve can also be furnished with auxiliary controls to meet the

need for additional functions, such as: pressure sustaining, rate of flow

control, pressure reduction, etc.
