Product Overview
Manual flanged ball valve is mainly used to cut off or put through the medium, can also be used for fluid regulation and control.Compared with other valves, ball valves have the following advantages:
1, the fluid resistance is small, the ball valve is one of the least fluid resistance in all valves, even if it is a reduced diameter ball valve, its fluid resistance is quite small.
2, the switch is fast and convenient, as long as the stem rotates 90°, the ball valve will comple...

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 Overview
Forged steel flange type high pressure ball valve closing parts of the ball around the center line of the valve body for rotation to open and close a valve, the seal is embedded in the stainless steel valve seat, the metal valve seat is provided with a spring, when the sealing surface wear or burn, under the action of the spring to push the valve seat and the ball to form a metal seal.Exhibit unique automatic pressure release function, when the valve lumen medium pressure mor...
Product Overview
JIS ball valve adopts split structure design, good sealing performance, not limited by the direction of installation, the flow of the medium can be arbitrary;There is an anti-static device between the sphere and the sphere;Valve stem explosion-proof design;Automatic compression packing design, fluid resistance is small;Japanese standard ball valve itself, compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in ...
