1.Design and manufacture according to API 6A and NACE MR0175;
2.Full size design, effectively eliminate pressure drop and eddy current, slow down solid particles in the fluid to wash the valve.
3.the valve plate adopts split - body expansion structure.
4.Achieve low torque operation and low wear during the switching process.
5.Metal seal between bonnet and body.
6.A soft seal or metal seal is used between the disc and the seat.
7.the sealing grease can be injected through the valve regularly to enhance the sealing performance of the valve.
8.the connection mode includes flange type, screw type and clamp type.
9.Non - rubber seal effectively protects valve chamber from well mud, sand, rock, etc
10.Simple, safe plate and seat design, no special tools required, easy to replace
