Product Description

First, British standard normally open pneumatic lined rubber diaphragm valve overview: EG6K41J British standard normally open pneumatic lined rubber diaphragm valve body is made of cast steel or cast iron, the use of PTFE or other rubber for the diaphragm, the close fit of the valve body and the diaphragm to provide valve body seal and seat seal, to ensure that the internal and external environment of the pipeline is completely isolated. EG6K41J normally open pneumatic lined rubber diaphragm valve is used to control non-corrosive or generally corrosive and highly corrosive media, the body cavity surface is not lined or covered with a variety of optional fluorine plastics and rubber, suitable for a variety of different working temperatures and fluid pipelines. It is composed of the cylinder and diaphragm valve, and the pneumatic actuator is used to drive the switch of the diaphragm valve, the ventilation is closed, and the air is opened. So as to achieve the medium cutoff function and connected in the pipeline. The interior of the valve is lined with different plastics, which can resist different degrees of corrosive media.
Second, British standard normally open pneumatic rubber lined diaphragm valve working principle:
EG6K41J normally open pneumatic rubber lined diaphragm valve ventilation closed, open and close is driven by the pneumatic actuator valve stem up and down movement to achieve. When the valve stem is in the upper, the spherical diaphragm bends upward the valve to form a conduction state. When the stem moves from the top down, the spool is driven to bend the diaphragm, forcing the diaphragm to tighten the seat area or close the path to the pipeline fluid.
Three, British standard normally open pneumatic rubber lined diaphragm valve product features:
1, the diaphragm can be replaced, low maintenance costs.
2, there is no stuffing box, so there is no leakage.
3, streamlined flow path, so that the pressure loss is small.
4. The opening and closing parts of the elastic seal ensure that there is no internal leakage.
5, the fluid channel is straight, so the fluid loss is smaller, less wear.
6, the valve body and the cover are separated by the middle diaphragm, so that the valve cover above the diaphragm, the valve stem and other parts are not eroded by the medium.
7, because the seal is elastic rubber diaphragm. Therefore, it also has good sealing and minimum closing force.
8, the surface of the valve body cavity of the diaphragm valve appears to have a variety of rubber for choice. Therefore, it has superior corrosion resistance characteristics.
