Coal Liquefaction.

Gasification

Photovoltaic industry;Polysilicon.

Medium Indluding H2S.

Strong-acid medium;HNO3,H2SO4;

2. Fireproof Structure Design

In the metal to metal sealing structure for the valve, the gasket is the stainless steel + flexible graphite and the packing is the flexible graphite. Therefore, reliable sealing of the valve can be ensured even in case of fire.

3. Reliable Sealing Performance
The unique ball grinding technology is adopted. Through rotation of the ball and the grinder at different positions, the ball surface will achieve high roundness and fineness. The low pressure sealing of valve seat is realized by spring pre-tightening. In addition, the position effect of valve seat is designed reasonably, which realizes high pressure sealing by the pressure of the medium itself. The sealing level of the valve meets the requirement of level IV B16.104.
