Altitude & Level Control Valves
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.
