Product features:
1.Flow resistance is small；
2.Piston seat, fire protection-antistatic structure design；
3.No limitation on the flowing direction of medium；
4.When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;
5.Spring loaded packing can be chosen;
6.Low emission packing can be chosen according to ISO 15848 requirement;
7.Stem extended design can be chosen;
8.Metal to metal seat design can be chosen;
9.DBB，DIB-1，DIB-2 design can be chosen；
10.The ball is fixed with a supporting plate and a fixed shaft;
Advantage:
Forged body material, much more stable perfomance than casting body which may have inter defects, since the body is made from forged material, no any repair and the surface looks good. Only solid ball is used to ensure a excellent performance. Compared with floating ball valves, the ball is fixed by both stem and bottom trunnion, so it have lower torque value. When the pressure in the cavity is high, it will push the spring seat move, make it preasure self release. Our trunnion mounted ball valves is strictly designed and produced as per API6D and related standard, 100% tested as per API6D. Painting can be custom appointed as per client requests, such as JOTUN, HEMPEL. TPI is accepted for either process inspection or final dimensional and testing inspection.
Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.
