Check Valve, 15,000 PSI - MAC Series

Parker's MAC Series (Ball and O-Ring) Check Valves provide unidirectional flow and shut-off for liquids and gases in medium pressure systems up to 15,000 PSI. These check valves utilize integral MPI Tube Fittings for a secure connection.

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 user's design preference. Parker's 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.

Parker's 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)
