• Accurate and Repeatable Level Control
• Easy Interface With Remote Control Systems
• Drip Tight Positive Shut Off
• Reliable Hydraulic Operation
• Easily Adjustable Control
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.

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Used on reservoirs where water is supplied and withdrawn through the Altitude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
2° slope from valve to reservoir to avoid air pockets.
Note: We recommend protecting tubing and valve from freezing temperatures.
