High Temperature And Pressure Ball Valve From High Vacuum To High Pressure Can Be Applied
Mar 02, 2018

High temperature and pressure ball valve is a new generation of high-performance ball valve for fluid regulation and control, its strength, safety, resistance to harsh environments and other special considerations in the design, suitable for a variety of corrosive and non-corrosive media. Work, the valve fluid pressure generated in the sphere all the forces transmitted to the bearing, the ball will not move to the seat, so the seat will not withstand excessive pressure, high temperature and pressure ball valve torque is small, the valve seat deformation Small, stable sealing performance, long service life, suitable for high pressure, large diameter occasions. Advanced spring pre-seat assembly with self-tightening features for upstream sealing.

High temperature and pressure ball valve flange bolted, sealed with PTFE reinforced inlaid stainless steel ring, the rear of the spring ring to ensure that the valve seat close to the ball, keep the seal. Upper and lower stems are Teflon non-stick coating on the bearings, with the highest temperature up to 290-300 ℃, low coefficient of friction, good wear resistance and excellent chemical stability, the bottom of the shaft is adjusted Film, to ensure that the ball and seal the location of the junction, so the operation effort.
