Manual Angle Ammonia Globe Valve

Product Description

Angle ammonia shut-off valves often use oxygen, nitrogen, hydrogen, argon and other gases. These gases are typically stored in dedicated high pressure gases. When in use, the gas pressure is reduced to the required range by the ammonia shut-off valve, and then finely adjusted by other control valves to make the gas input into the system.

Instructions

(1) Ammonia gas pressure reducing valves are available in many sizes depending on the requirements of use. The highest import pressure is mostly, the minimum import pressure is not less than 2.5 times the export pressure. There are many export pressure specifications, generally, the highest outlet pressure is.

(2) When installing the ammonia gas pressure reducing valve, determine whether the connection specifications are consistent with the joints of the system. The ammonia shut-off valve is connected by a hemispherical surface, and the nut is fully fitted by tightening the nut. Therefore, the two hemispheres should be kept clean during use to ensure a good airtight effect. High pressure gas can be used to blow off dust before installation. If necessary, a material such as polytetrafluoroethylene may be used as the gasket.

(3) The shut-off valve for ammonia should be strictly prohibited from contact with grease to avoid fire accidents.

(4) When stopping the work, the residual gas in the pressure reducing valve should be drained, and then the adjusting screw should be loosened to prevent the elastic component from being deformed by pressure for a long time.

(5) The shut-off valve for ammonia should avoid impact vibration and should not be in contact with corrosive substances. The use method and precautions for these ammonia shut-off valves are basically the same as those for ammonia. However, it should also be noted that dedicated ammonia valves are generally not used for other gases. In order to prevent misuse, some ammonia valves and cylinders use a special connection. For example, both hydrogen and propane use left-hand thread, also called reverse thread, and special care should be taken during installation.
