The shell has two options: forging and casting. The surface of valve is smooth and even, so that the valve could meet the requirements that working in a high temperature and high pressure condition.
Matched with special material ensure the hardness and the hardness difference of sealing surface are in high values. Precisely polishing makes the surface is cleaned as a mirror, which is corrosion resistance so as to prolong the service life.
The back sealing design efficiently protects the sealing packing from leakage.
The surface of stem is precisely polished and processed by harden treatment so as to improve the performances of abrasion resistance and erosion resistance, efficiently decreasing the open/close torques, make the valve is much easier to be operated.
It adopts special corrosion inhibition packing structure, which is high temperature resistance and high pressure resistance, self-lubricated and there is no corrosion. The design could decrease fracture when it is starting and closing, so that the stem surface is protected from being corroded, and then avoiding leaking.
The design of bi-directional pressure-bearing sealing structure meets various special requirements of severe working conditions.
It adopts bonnet self-sealed design, based on which, the more pressure loading, the sealing performance is more reliable.
