Description
EXTREMELY RESISTANT TO WEAR CHECK VALVE – PERSTA 640DJ
The PERSTA 640DJ is our check valve for high pressure with weldable connection or DIN flange (ASME version available) . p >
The valve has welded seats for better sliding performance , a locking device with a pin for optimal alignment of the disc to the body of the seat .
The freewheel hinge pin serves to reduce friction and wear of the packing. Part-turn actuator for fast and safe closing.
ISO5211 connection for mounting a pneumatic or hydraulic actuator. Symmetrical design body that allows the actuator to be installed on one side or the other .
The nominal pressure range is 40-250 bars. The maximum temperature is -10ºC to 600ºC .
