DZ40Y cryogenic valve

Working principle of the product and application:

Cryogenic valve compact structure, small volume, good rigidity, safe and reliable. Closed (ram) using elastic structure, in the work can automatically compensate for deformation of body caused by abnormal load or temperature. Therefore, reliable sealing, and won't produce gate wedge to death. The seat, seat for replacement type can be any combination with close seal face material matching, in order to satisfy the requirement condition, prolong service life.

Gate valve is suitable for methane, liquefied natural gas at low temperature, has ene, 2

      Product structure features:

1, to prevent abnormal midplane booster, set up a pressure relief hole on the inlet side of the gate

2, according to the working temperature of the valve cover at the top of the length, ensure reliable sealing stem packing

3, according to the working temperature reasonable choice packing, gaskets and other parts of the material

4, strictly control the material chemical composition and mechanical properties such as low temperature impact toughness index

5, use a variety of piping flange standards and sealing surface type, suitable for all kinds of engineering needs
