Cla-Val - Hydraulic Altitude & Level Control Valves - 210-03 & 610-03 Altitude Valve for One-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 210-03 and 610-03 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 a high water level. Water is withdrawn from the reservoir through a separate discharge line or through a check valve located in a by-pass line around the altitude valves. The valves delay opening until the water in the reservoir lowers to the desired level. The low level is adjustable from 1 to 15 feet from the high water shut-off point.
Used on reservoirs where water is withdrawn from the reservoir through a separate line. When the water level lowers to the desired opening point, the pilot control opens the main valve to refill the reservoir. The difference between the high-level shut-off and the low-level opening is adjustable between a minimum of one foot and a maximum of fifteen feet.
