Description
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.
The CLA-VAL 210-31 is one way flow only. The reservoir pressure sensing line should be 20 mm minimum I.D. installed with 2° slope from the valve to the reservoir to avoid air pockets.
Check Valve prevents backflow into the network if P2 > P1.
