(1) According to different use requirements,
Gate Valve have many specifications. The high inlet pressure is mostly, and the low inlet pressure is not less than 2.5 times the outlet pressure. There are many outlet pressure specifications, generally, and the high outlet pressure is.
(2) When installing the Gate Valve, you should determine whether its connection specifications are consistent with the joints of the cylinder and the use system. The
Universal Valve and the cylinder are connected by a hemispherical surface, and the two are completely matched by tightening the nut. Therefore, when using, the two hemispherical surfaces should be kept smooth to ensure good airtightness. Dust can be blown away with high-pressure gas before installation. If necessary, materials such as polytetrafluoroethylene can also be used as gaskets.
(3) When stopping work, the remaining air in the Universal Valve should be released, and then the adjusting screw should be loosened to prevent the elastic element from being deformed under pressure for a long time.
(4) The Gate Valve should be strictly prohibited from contacting grease to avoid fire accidents.
(5) The Universal Valve should avoid impact and vibration, and should not come into contact with corrosive substances.
