Cla-Val - Hydraulic Pilots & Accessories - CDS7 Altitude Pilot Control ***
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.
The Cla-Val Model CDS7 Altitude Pilot Control is a spring-loaded, three-way, diaphragm-actuated control that provides high-level shutoff for Cla-Val 211 Series Altitude Control Valves. The CDS7 controls the high water level in a reservoir or tank without the need for floats or other devices. It is a non-throttling pilot that remains fully open until the reservoir reaches the high-level shutoff point.
High accuracy is assured by remotely sensing the pressure head of the reservoir or tank. The single adjusting nut can be easily set in the field to close the main valve when the liquid level reaches the desired high-level set-point within the standard adjustment range.
