Parker’s MACB series (Ball Check Valve) 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 1000°F (538°C). 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.

Parker’s MAC series (O-Ring Check Valve) provides unidirectional flow and tight shut-off formore
