Ball screw gate valves are designed for large caliber, high-pressure manual valves. The valve combines the tail balance lever and the unique ball principle to make its operation light, low torque, and easy to operate. Its diameters range from 3 1/16 "to 9" and its pressures range from 10,000 psi to 20,000 psi.

1. Two-way downstream sealing structure, which improves the service life;
2. Fixed metal seal (between gate and seat and seat and body);
3. Simple and reliable gate and seat design can reduce field service;
4. Sealing ring between seat and body helps seal at low pressure. They also prevent granular contaminants from entering the body chamber and sealing area;
5. Stem seal design covers all pressure classes, temperature ranges, and all fluid conditions encountered in wellhead and manifold environments;
6. Metal seal between bonnet and valve body, up to 20000psi working pressure;
7. Reverse stem seal structure allows the valve to replace stem seal under pressure drive;
8. To ensure safety, a grease injection device can be placed on the stem after the inverted seal. The device can be placed on the bonnet to eliminate body leakage;
9. Ball screws can effectively improve the switching efficiency and reduce the switching torque, which is more conducive to opening and closing the valve easily and quickly.
