Design characteristics
Purge valves with counter weights are valves with a normal primary closing system and a secondary closing system operated by the counterweight falling.The normal closing system Is designed to provide a seal for a long period.The secondary closing system Is a quick but provisional closing,see below the design working pressures.
Adjusting the counterweight
Full opening of the secondary closing system should occur when the counterweight is positioned near “1 o’clock when facing the counterweight side of the valve. The counterweight position(conical fixing)must be oriented depending on the purge valve fitting position. The counterweight should fall down by itself.
Operation
If the primary valve is open, the counterweight is in the high position, the purge valve is open. To close the purge valve, let the counterweight fall. The primary closing system can then be operated manually. The cap should be replaced after closing the primary valve.
