Parker MAC Series MPI Check Valves

派克的 MAC 系列 MPI 止回閥與當今市場上的普通止回閥相比具有獨特的設計。首先，它們能夠承受高達 15,000 PSI 的工作壓力。然后它們可用作球形止回閥，另一種是 O 形環止回閥，具體取決于用戶的設計偏好。Parker 的 MACBL 系列（球型止回閥）可在不強制要求密封關閉的情況下防止反向流動。當壓差低于開啟壓力時，閥門關閉。對于全金屬組件，閥門可在高達 650°F (343°C) 的溫度下使用。球和提升閥是一個整體設計，以確保積極的、在線的就座，而不會“喋喋不休”。提升閥主要設計用于具有最小壓降的軸向流動。

Parker 的 MACL 系列（O 形環止回閥）為液體和氣體提供單向流動和高可靠性的嚴密關閉。當壓差低于開啟壓力*時，閥門關閉。（不用作泄壓閥）

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)
