Cla-Val 270-01 : ON/OFF Altitude Valve
CLA-VAL 270-01 is typically designed for closed reservoirs where water is withdrawn through a separate line. The valve opens when the liquid level reaches a preset minimum level and closes drip tight when the tank reaches the preset adjustable maximum level. The desired water level is set by adjusting the spring force. The pilot control operates on the differential in forces between a spring load and the water level in the reservoir.
