Parker Check Valves
单向阀，15,000 PSI - MAC 系列 Check Valve, 15,000 PSI - MAC Series

派克的MAC系列 (浮球和O形圈) 单向阀控制液体和气体的单向流动和密闭，适用于压力至 15,000 PSI的中压系统。此类单向阀应配合MPI管接头使用，以实现安全连接. 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.

派克 MAC 系列 MPI 单向阀设计新颖。首先，MAC系列MPI单向阀工作压力可达15,000 PSI。其次，此类单向阀有浮球单向阀和O型圈单向阀供用户选择派克MACBL系列 ((浮球单向阀) 以防回流，适用于非强制性气密关闭的场合。当压差低于开启压力时，阀门关闭。阀门采用全金属结构，温度可达 650°F (343°C)。浮球和提动头一体化，使轴向压降更小。 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.

派克MACL系列 (O型圈单向阀) 控制液体和气体的单向流动和密闭，性能稳定。当压差小于开启压力时，阀门关闭。(不能作安全阀使用) 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)
