balanced pneumatic globe valve principle:
1. Balanced pneumatic globe valve is composed of two parts: gate valve and relay control. The other part is equipped with pneumatic triplets to ensure the long-term reliable operation of gate valve.
2. Under the condition of all normal gas paths, when the relay is powered on, the air inlet at the upper end of the cylinder and the piston rod of the driver cylinder operate downward, and the gate valve is turned off. When the relay stops, the gate valve opens.
Installation, application and maintenance of balanced pneumatic cut-off:
1. The balanced pneumatic stop valve can be installed in any position, preferably in a horizontal position. If it is installed in its installation position, the installation position of the pneumatic triad must be adjusted so that the pneumatic triad can be installed in a horizontal position.
2. The valve is equipped with two-position five-way relay:(DN24V), pneumatic triad, muffler and PLC to complete the automatic control system.
3. Carry out maintenance and maintenance on time for balanced pneumatic stop valve and pneumatic trio. When it is found that the water flow in the test standard orifice plate on the gate valve casing indicates that the hydraulic seal in the gate valve is damaged, it must be immediately replaced to ensure the normal application of the gate valve.
