Principle Of Pneumatic Valves And Selection Principles
- Nov 03, 2016 -

Pneumatic cut-off valve or valve, valve is one of the most widely used as it is popular, due to less friction between sealing surface in the process of opening and closing, more durable, opening height is small, easy to manufacture, easy maintenance, applies not only to low-voltage and apply pressure. Cut-off valve closed principle is, depends on valve bar pressure, the sealing surface of valve and valve seat sealing surface is tightly attached to prevent media circulation. One-way flow valves only medium, the installation direction. Structure length is greater than the cut-off valve gate valve and fluid resistance, long runs, sealing reliability is not strong.
