Cla-Val Pacific's Models 210-01 and 610-01 Altitude Valves control the high water level in reservoirs without the need for floats or other devices. They are non-throttling valves that remains fully open until the shut-off point is reached. This valves are designed for one-way flow only.
This series of valve is hydraulically operated and pilot controlled. The pilot control operates on the differential in forces between a spring load and the water level in the reservoir. The desired high water level is set by adjusting the spring force. The pilot control measures the reservoir head through a customer supplied sensing line* connected directly to the reservoir.
Advantages include:
- Accurate and Repeatable Level Control
- Drip-Tight, Positive Shut-Off
- Reliable Hydraulic Operation
- Easily Adjustable Control
- Completely Automatic Operation
Typical applications:
Used on reservoirs where the water is withdrawn through a separate line or through a bypass equipped with a check valve. The valve opens to refill the reservoir when the water lowers below the shut-off level.
