Ball Screw Operation Gate Valve

Ball Screw Gate Valves The body and flanges are integral (non-welding). Shot Blasting for every parts of valve. Phosphating to improve corrosion resistance. rac valves - ball screw gate valves supplier is a type of large bore gate high pressure valve which were improved from Cameron FLS-R gate valve, its the main component of frac tree, the frac valve is often used on the top of the wellhead on high pressure oil well, can do the frac job for Isolating the fluid from the well. The body and flanges are integral (non-welding). Shot Blasting for every parts of valve. Phosphating to improve corrosion resistance. Features: Valve with Ball Screw Ball screw structure lowers operating time Gate valve design Stem structure is pressure balanced with switch indicator wellhead equipment manufacturers Specifications: Applies to big bore high pressure system Working pressure:2000 PSI-20000 PSI Connection: Flange* Thread Union BW Size: 1 13/16"-7 1/16' Working temperature:K.

Gate valves(ball screw operation) The ball-screw operation gate valve was developed for large-bore applications, to provide manual operation at full working pressure with remakably low opening torque.The design eliminates the need for gear-type torque multipliers, and results in quicker, safer operations. The ball-screw operation gate valve shares the basic features of the "ls"series:a slab gate, patented seat seal, non-elastomeric stem seals, and metal-to-metal sealing.However, the ball-screw operation gate valve has a lower balancing stem and unique ball screw mechanism Size:3-1/16", 4-1/16", 5-1/8", 7-1/16" Wp:10, 000psi, 15, 000psi Temperature:l u, pu Mat's:aa-ff psl:1-4 pr:1-2 Honorary certificate Our products have been iso9001 certified and attained api 6a, 6d, api 7, 7k, and api 16a&16c approvals of american pertroleum insitute.All products are fully designed and manufactured in accordance with api, ansi, gb(national standards)and sy(industry standards)standards.

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. Product features: 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.
