Autoclave Engineers Low Pressure Pipe Ball Check Valve - P

Parker Autoclave Engineers P Series Low Pressure Pipe Ball Check Valves prevent reverse flow where leak-tight shut-off is not mandatory. When differential drops below cracking pressure, valve closes. With all-metal components, valve can be used up to 400°F (204°C). See Technical Information section for connection temperature limitations. (Not for use as a relief valve.) Ball and poppet are an integral design to assure positive, in-line seating without “chatter”. Poppet is designed essentially for axial flow with minimum pressure drop. Materials: 316 Stainless Steel: body, cover, ball poppet, cover gland. 300 Series Stainless Steel: ball, spring. Special material check valves may be supplied with four flats in place of standard hex.
