 Design characteristics       

         Purge values with counterweight are values 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.  

 

 

 Secondary closing

 

pressure against which the counterweight falling will seal the valve		increase in pressure resistance after closing
DN8	25BAR	25BAR
DN15	Max7.5 BAR	25BAR

 

 

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 value.

The counterweight position(conical fixing)must be oriented depending on the purge value fitting position.

The counterweight should fall down by itself.

 

 

Operation

If primary valve is open,the counterweight si in the high position, the purge 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.
