Because the operating pressure is above the swivel plate, it helps the valve close and also contributes to pressure (control function B or I, CFB or CFI). sealing the valve seat. The valve opens via pilot pressure. As the medium is present under the swivel plate, the operating pressure contributes to the opening of the valve. WARNING WARNING Risk of injury from pressure surge. Valve leak if there is too little minimum pilot pressure or high A pressure surge could cause lines and the device to burst.
