【Valve Knowledge】Valve Performance Inspection

Valve inspection is extremely important, as it determines whether the valve can operate normally and safely.

The selection of valves is based on specific application needs and system requirements.

(1) Valves must be manufactured in accordance with the relevant technical standards, design drawings, technical documents and order contracts. They can only be shipped after passing the inspection.
(2) When there are special requirements, they should be specified in the order contract, and the inspection and supply should be in accordance with the specified requirements.
(3) The manufacturer should supply the products required by the user within the period specified in the contract.

Valves are important control devices in fluid pipeline systems. Their functions: connecting and cutting off media; preventing media backflow; regulating media pressure and flow; separating, mixing or distributing media; preventing media pressure from exceeding the specified value to ensure safe operation of pipelines or equipment.

In industrial pipeline systems and various civil pipeline facilities, valves play a vital role. They can control the flow, pressure and flow direction of fluids. The choice of valve connection method is directly related to the performance, reliability, installation convenience and subsequent maintenance cost of the entire pipeline system.
