Description
CHECK VALVE WITH SWING EXTREMELY RESISTANT – PERSTA VALTRA 640AA
The PERSTA VALTRA 640AA is our globe valve for high pressure with a weldable connection or DIN flange (ASME version available) . The valve has a welded body and disc seat for maximum wear resistance. The disc has a flexible shaft in the hinge for optimal alignment of the disc to the seat of the valve. The crank rests on the hinge pin to separate the gasket which, together with the appropriate materials, provides extra resistance to wear . Inner shaft to limit leakage . The nominal pressure range is 40 bar. The maximum temperature is -10ºC to 400ºC .
