Pneumatic Stainless Steel gate valve

Pneumatic Gate Valve: a valve driven by compressed air.

It is not perfect in the current market economy environment to define the specification, category and working pressure when purchasing pneumatic valves to meet the procurement requirements. For the sake of product competition, manufacturers of pneumatic valves have made different innovations under the concept of unified design of pneumatic valves, forming their own enterprise standards and product personality. Therefore, it is necessary to put forward technical requirements in detail when purchasing Pneumatic SS Gate Valve , and coordinate with the manufacturer to reach a consensus as an annex to the Pneumatic Valve purchase contract.

General requirements

1) The specification and category of pneumatic valve shall meet the requirements of pipeline design documents.

2) The model of pneumatic valve shall indicate the national standard number requirements. If it is an enterprise standard, the relevant description of the model shall be indicated.

3) The working pressure of Pneumatic SS Gate Valve shall be ≥ the working pressure of the pipeline. On the premise of not affecting the price, the working pressure that the valve can withstand shall be greater than the actual working pressure of the pipeline; When the pneumatic valve is closed, any side shall be able to withstand 1.1 times of the valve working pressure without leakage; When the valve is open, the valve body shall be able to withstand twice the working pressure of the valve.

4) The manufacturing standard of pneumatic valve shall state the national standard number. If it is an enterprise standard, the purchase contract shall be attached with enterprise documents
