Pneumatic Cast Steel Stainless Steel Globe Valve For Water Steam Oil Pipeline Use
Product Introduction:
Pneumatic globe valve is an important control valve composed of pneumatic actuator and globe valve body, widely used in the control and regulation of gases, water, steam and other media in the industrial field
The axis of the valve stem of the globe valve is perpendicular to the sealing surface of the valve seat, and the opening or closing stroke of the valve stem is relatively short, with a very reliable cut-off action, making this pneumatic valve very suitable for use as a medium for cut-off, regulation, and throttling.
Globe valves belong to forced sealing valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters valve 6 from below the valve disc, the resistance that needs to be overcome by the operating force is the friction force between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be larger, otherwise it will cause the valve stem to bend.

Product features:
1. Quick cut: After receiving the control signal, the pneumatic globe valve can quickly cut off the flow of gas or liquid in the pipeline, achieving the goal of rapid control.
2. High sensitivity: Pneumatic globe valves have sensitive response speed and action sensitivity, which can adapt to high-frequency control requirements.
3. Energy saving: Pneumatic globe valves have the advantage of saving energy. Compared with electrical control, pneumatic control systems are more energy-efficient and have better economy.
4. Convenient maintenance: the maintenance and replacement of components for pneumatic globe valves are relatively easy, and there is no need to disconnect the pipeline. The maintenance process is simple, and the maintenance cost is relatively low.
5. Good durability: The durability of pneumatic globe valves is good because the pneumatic control components have mechanical and chemical properties, are not easily damaged, and have a long service life.
6. Safe and reliable: The pneumatic globe valve adopts safety measures such as gas source self-control valve to ensure work safety, and has a simple structure that is not prone to failure.
