Zeco’s trunnion ball valve is a new generation of high performance ball valve, suitable for long-distance pipeline and general industrial pipeline, its strength, safety, resistance to harsh environment and other special considerations in the design, suitable for a variety of corrosive and non-corrosive media. Compared with the floating ball valve, it works, the fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the trunnion ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced spring - loaded seat assembly with self - tightening features for upstream sealing.Each valve has two seats and can be sealed in each direction, so the installation has no flow restriction and is two-way.This valve is normally installed horizontally. The trunnion ball valve has two kinds of body structure, two kinds of three kinds, the middle flange is connected with bolts, the sealing is made of reinforced polytetrafluoroethylene embedded in the stainless steel ring, the back of the steel ring has a spring to ensure the seat is close to the ball, keep the seal.The upper and lower stem are equipped with PTFE bearing to reduce friction and labor saving operation. The bottom of the small shaft is equipped with adjusting plate to ensure the joint position of the ball and the sealing ring.Full size: the valve flow bore is the same as the inside diameter of the line for line cleaning.
