FLANGED CHECK VALVE HIGH PERFORMANCE
WITH CLAPPER
PERSTA 640AA
Range: DN50-250
Pressure: PN40
Temperature ratio: -10ºC to 400ºC
Description
CHECK VALVE CLAPPER EXTREME RESISTANCE – PERSTA 640AA
The PERSTA 640AA is our high pressure globe valve with DIN flange connection (ASME version available) . Hardened seats with a 13% / 17% chrome steel coating for extreme wear resistance. Locking disc with curved cavity in the lever to improve movement and alignment of the disc with the seat . The lever rests on the bolt thanks to a separating washer that, together with a good selection of material, improves wear resistance. The nominal pressure range is 40 bar. The maximum temperature is -10ºC to 400ºC .
