MURPHY Pneumatic Valves for Fuel Gas Shutoff Models M2582-P and M5180-P
M2582-P / M5180-P气动控制燃油切断阀
M2582-P和M5180-P是气动控制的燃油切断阀,可自动或半自动打开和关闭。气动控制压力可以是空气、油或气体。当控制压力不足时,手动杆有助于打开阀门。当适当的排气和维护时,气体逸出排气口在关闭后从阀门中释放截留的气体。The M2582-P and M5180-P are pneumatically controlled fuel shutoff valves that open and close automatically or semi-automatically. The pneumatic control pressure can be air, oil or gas. A manual lever aids in opening the valve when control pressure is insufficient. A gas escape vent, when properly vented and maintained, releases trapped gas from the valve after shutoff. Basic operation is:
Automatic: As the control pressure/vacuum increase the valve will open.When the control pressure/vacuum decreases, the valve will close.
Semi-Automatic: If the control pressure/vacuum is too low and the valve does not open automatically, it can be opened manually by lifting the built-in lever arm and setting the latch. The latch resets automatically when control pressure rises enough to release it.
M2582-P is for 1-inch (25 mm) gas lines. It automatically opens at 5 psi (35kPa) [0.34 bar] and fully opens the seat at 15 psi (103 kPa) [1.02 bar]. The
valve can be manually opened with the lever and latch against inlet pressure of 80 psi (552 kPa) [5.52 bar]. The latch will release after pilot pressure
reaches 11 psi (17kPa) [.17 bar].
M5180-P is for 2-inch (52 mm) gas lines. It automatically opens at 5 psi (35kPa) [0.34 bar] and fully opens the seat at 15 psi (21 kPa) [.21 bar]. The
valve can be manually opened with the lever and latch against inlet pressure of 100 psi (689 kPa) [6.89 bar]. The latch will release after pilot pressure
reaches 11 psi (17kPa) [.17 bar].
