Product Description
Ball valve after more than half a century of development, now has become a widely used main valve class.The main function of the ball valve is to cut off and connect the fluid in the pipeline;It can also be used for fluid regulation and control.Ball valve has the characteristics of small flow resistance, good sealing, quick switching and high reliability.
Ball valve is mainly composed of valve body, valve cover, valve stem, ball and sealing ring and other parts, belongs to...
Product Overview
Q47 type fixed ball valve compared with the floating ball valve, it is working, 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 fixed 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 pre - seat assembly with ...
Product Description
This series product adopt new floating type sealing structure, is applicable to pressure is not greater than 15.0 MPa, temperature – 29 ~ 121 ℃ on the oil and gas pipeline, as control opening and closing of the medium and adjusting device, the product structure design, select material appropriate, strict testing, convenient operation, strong anti-corrosion, wear resistance, erosion resistance,It is an ideal new equipment in petroleum industry.
1. Adopt floating valve...
