GB fixed stainless steel ball valve Q347F

Fixed ball valve, is a new generation of high-performance ball valve for long-distance pipelines and general industrial pipelines, its strength, safety, resistance to harsh environmental design in the special consideration for a variety of corrosive and non-corrosive media . It is compared with the floating ball valve, work, the valve before the fluid pressure generated in the sphere of all the forces transmitted to the bearing, will not move the ball to the valve seat, so the valve seat will not be too much pressure, so fixed ball valve Small torque, small valve seat deformation, stable sealing performance, long service life, suitable for high-pressure, large-caliber occasions. Advanced spring pre-seat assembly with self-tightening feature for upstream sealing. Each valve has two seats, each direction can be sealed, so the installation does not flow restrictions, is two-way. The valve is generally horizontally mounted.

The fixed ball valve has two block type and three block type two kinds of valve body structure, the middle flange is connected with the bolt, the seal adopts the reinforced PTFE embedded in the stainless steel circle, the steel ring has the spring to ensure the valve seat is close to the sphere, Keep the seal. Upper and lower stem are equipped with PTFE bearings, reducing friction, operation effort, the small axis at the bottom with adjustment piece, to ensure that the ball and the ring at the location. Full Diameter: The valve flow aperture is the same as the inner diameter of the pipeline to allow the line to be cleaned.
