Parker's MAC Series MPI™ Check Valves offer distinct designs over general check valves found in the market today. First, they are capable of working pressures up to 15,000 PSI. Then they are available as a ball check valve and the other is an o-ring check valve depending on the users design preference. Parkers MACBL 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 650°F (343°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.
Parkers MACL series (O-Ring Check Valve) provides unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure*, valve shuts off. (Not for use as a Relief Valve)
