Cla-Val - Hydraulic Altitude & Level Control Valves - 210-02 & 610-02 Altitude Valve for Two-Way Flow with Delayed Opening ***
Cla-Val manufactures several different types of level control valves. Non-modulating float valves open fully when the liquid level in a tank reaches a pre-set low point. The opening operation allows for the tank to be refilled to a pre-set high point, at which time the valve closes drip-tight.
Modulating float valves maintain a constant liquid level in a storage tank by compensating for variations in supply or demand and are used to control the flow into or out of a tank by either opening or closing on a rising level.
Cla-Val Altitude Control Valves regulates the high water level in reservoirs without the need for floats or other devices. These non-throttling valves remain fully open until the pre-set shut-off point is reached. Altitude valves can be configured for one-way or two-way flow depending on system requirements and can be furnished with auxiliary controls for multiple functions such as pressure sustaining, pressure reduction, rate-of-flow control, solenoid override or other parameters as needed.
Cla-Val 210-02 and 610-02 Altitude Valves control the high water level in reservoirs without the need for floats or other devices. They are non-throttling valves that remain fully open until the shut-off point is reached. These valves close at the high water level, and for return flow, delay its opening until the pressure at the valve inlet lowers to a preset adjustable pressure of one to seven pounds.
These valves can also be furnished with auxiliary controls to meet the need for multiple functions, such as pressure sustaining, pressure reduction, rate of flow control, solenoid override, etc.
Used on reservoirs where water is supplied and withdrawn through the altitude valve. The valve closes at the high water level. When the pressure at the valve inlet lowers to the desired opening point, the pilot control opens the main valve for return flow to the system.
