Flange pneumatic valve installed in a different environment

Pneumatic valve flange pneumatic valve and gate is belong to the same type of pneumatic valves, the difference is that its closure is the individual, body around the center line of the pneumatic valve body rotation to achieve a kind of pneumatic valve opening and closing. Pneumatic valve in the pipeline is mainly used for cutting, distribution, and a role in the direction of the flow of the medium change.
the flange of the pneumatic valve outdoor installation: pay attention to the need to be equipped with protective measures. For example, in the outdoor environment, the installation of flange by pneumatic valve needs some protect themselves from blowing sand and facilities of rain, high temperature resistant performance is poorer material of flange by pneumatic valve need to be equipped with facilities to block direct sunlight.
pneumatic valve installed in low temperature environment: the need to consider the flange by pneumatic valve material. If material is not resistant to low temperature, can be considered for similar performance but low temperature resistant ability stronger other pneumatic valves. And under the environment of high temperature, which can be reference to the practice of low temperature environment, but it is important to note that if the temperature is not high, ventilation cooling method can be taken to its protection.
pneumatic valve in full open or full close, the body and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface.
