Ammonia globe valve

First, the structural characteristics and uses
1, through the flange for the square structure, the stem rod connection. 
2, the valve body sealing surface using ball convex shape, and the valve to line seal. 
3, the sealing surface with Babbitt, sealing performance, long service life.

Ammonia cut-off valves often use oxygen, nitrogen, hydrogen, argon and other gases. These gases are generally stored in a dedicated high-pressure gas. When using the ammonia through the cut-off valve to gas pressure drop to the desired range of experiments, and then through the other control valve fine-tuning, the gas input system. The most commonly used pressure reducing valve for the ammonia valve, referred to as ammonia valve. 

Second, performance specifications

Third, the main size and weight

Fourth, the appearance and working principle
Ammonia valve high pressure chamber and the cylinder connection, low pressure chamber for gas exports, and access to the use of the system. Indication of high pressure gauge is the pressure of gas stored in the
