Features
1.Full-bore design effectively eliminates pressure drop and eddy currents and slows down solid particles in the fluid
flushing of valves;
2.Unique sealing design, so that the switching torque is greatly reduced;
3.Metal seals are made between the bonnet and the valve body, the valve plate and the valve seat ring;
4.Metal sealing surface spray (overlay) welding cemented carbide, with good wear resistance, corrosion resistance;
5.The seat ring is fixed by the fixed plate to maintain good stability;
6.The stem is equipped with an inverted sealing mechanism to facilitate the replacement of the stem sealing ring with pressure.
Features
1.The inside of the valve body does not use any rubber as the sealing material;
2.The valve body is made by die forging compression one-time forming process;
3.The valve body, valve seat and valve plate are all metal-to-metal seals,
4.It has good sealing performance and long service life;
5.The valve stem has a back seal, and the valve stem seal packing can be replaced with pressure;
6.The valve operation switch torque is light. It can be operated by one person under pressure;
7.Spare stem safety pin protects the stem from being sheared.
Features
1.With balanced tail stem to balance the stem load and reduce the valve rod thread and bearing load, reducing the operating torque;
2.Open rod structure, which can indicate the valve opening and closing situation;
3.The valve stem is equipped with an inverted sealing mechanism for easy replacement with pressure Stem seals;
4.A sealing grease injection valve is provided on one side of the bonnet for easy replenishment
Sealing grease to improve the sealing performance and sealing performance of valve plate and valve seat Lubricating properties
