MURPHY Pneumatic Valves for Fuel Gas Shutoff Models M2582-P and M5180-P
M2582-P / M5180-P 气动燃气切断阀
用于燃气关闭的气动阀
这些阀是气动控制的燃油截止阀。它们设计为自动或半自动打开和关闭。
MURPHY 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。
Pneumatic Valves for Fuel Gas Shutoff Models M2582-P and M5180-P
M2582-P / M5180-P气动燃气切断阀
- 操作是自动或半自动的
- 气动控制压力可以是空气、气体或油
- 2 英寸型号。或 1 英寸。（51 mm 或 25 mm） 燃气管路
气动控制压力可以是空气、油或气。当控制压力不足时，手动杆有助于打开阀门。气体排放口在适当通风和维护的情况下，会在关闭后从阀门中释放滞留的气体。
基本操作为：
自动：随着控制压力/真空度的增加，阀门将打开。当控制压力/真空度降低时，阀门将关闭。
半自动：如果控制压力/真空度过低，阀门不自动打开，可以通过抬起内置杠杆臂并设置闩锁来手动打开。当控制压力上升到足以释放时，锁存器会自动复位。
M2582-P 适用于 1 英寸（25 毫米）气体管路。它在 5 psi （35kPa） [0.34 bar] 的压力下自动打开，并在 15 psi （103 kPa） [1.02 bar] 的压力下完全打开阀座。阀门可以用杠杆手动打开，并在入口压力为 80 psi （552 kPa） [5.52 bar] 的情况下锁定。当先导压力达到 11 psi （17kPa） [.17 bar] 时，闩锁将松开。
M5180-P 适用于 2 英寸（52 毫米）气体管路。它在 5 psi （35kPa） [0.34 bar] 时自动打开，并在 15 psi （21 kPa） [.21 bar] 时完全打开阀座。阀门可以用控制杆手动打开，并在入口压力为 100 psi （689 kPa） [6.89 bar] 的情况下锁定。当先导压力达到 11 psi （17kPa） [.17 bar] 时，闩锁将松开。
M2582-P/M5180-P Pneumatic Valves for Fuel Gas Shutoff
These valves are pneumatically controlled fuel shutoff valves. They are designed to open and close automatically or semi-automatically.
Operation is automatic or semi-automatic
Pneumatic control pressure can be air, gas or oil
Models for 2 in. or 1 in. (51 mm or 25 mm) fuel gas lines

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].
