Shanghai double high fixed worm ball valve, Hebei double high valve and Tianjin double high ball valve
Flanged worm wheel fixed ball valve product overview:
Q347 type flange fixed ball valve is a new generation of high performance ball valve, the valve has two type and three type two body structure, the flange bolts assembled and sealed with PTFE inserts into the stainless steel ring, wheel without the rear spring to ensure the seat close to the ball, keep the seal. There is no PTFE bearing on the upper and lower stem, reducing friction, operation saving, no adjustment plate at the bottom of the small axis, and ensuring the position of the ball and the sealing ring. Full path: the valve flow pore diameter is consistent with the inner diameter of the pipeline, so that the pipeline can be cleaned. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety and harsh environment are specially considered in design. It is suitable for various corrosive and non corrosive media. It compared with the floating ball work force, fluid pressure before the valve resulting in the ball on all transferred to the bearing, not to move the ball to the seat, the seat would not put too much pressure, so fixed valve torque is small, the valve seat sealing small deformation, stable performance, long service life, suitable for high pressure large caliber occasions. The advanced spring pre - seat assembly has self tightening characteristics to realize the upstream seal. Each valve has two seats that can be sealed in each direction, so there is no direction limit for the installation, and it is two-way.
