Почему выбирают наши шаровые краны
Tight Shut Off & Low Emission
Several unique design features, excellent sealing materials and a strong body make the valve an excellent choice for shut-off with Zero Leakage under pipeline pressure.
Super Fire Safe Design
Excellent material of graphite, O-ring, gasket and advanced sealing structure are applied to make the valve with reliable sealing even after the fire.
Anti Blow-out Stem&Anti-Static
An Independent stem and integral shoulder can prevent the stem from blow-out and ensure the safety of the operator. The anti-static device on the ball&stem makes the valve free from sparking.
Fully Customizable Design
Trunnion/Floating, DBB/DIB, Soft/Metal and different materials are available. The valve design is fully customizable to meet customers' project specifications.

Seat Structures
DBB-Double Block and Bleed: Single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of venting/bleeding the cavity between the seating surfaces. The single piston effect is the standard design for trunnion-mounted ball valves. Pressure from both the upstream and downstream sides pushes the seat rings against the ball. If the force created by the body cavity pressure is greater than the preloaded spring force plus the force created by the pressure from the upstream or downstream side, the seats are pushed away from the ball. Thus, any overpressure in the body cavity is released automatically in the valves' fully open or fully closed position.
DIB-Double Insolation and bleed: Single valve with two seating surfaces, each of which, in the closed position, provides a seal against pressure from a single source, with a means of venting/bleeding the cavity between the seating surfaces. Double piston effect seats are pressure energized in both directions. So the seat rings are always pushed against the ball by the pressure from upstream/downstream or from the cavity. If the upstream seat fails, the downstream seat can still ensure a tight seal.

Anti-blowout Stem& Anti-static Device
The stem is made separately from the ball. The lower end of the stem is designed with an integral shoulder to be blowout-proof.
The electrical continuity of the ball, stem, and body is ensured by the device(spring and ball) to avoid dangerous sparking during the operation.

Emergency Sealant Injection System
In an emergency case, when the sealing materials(soft seat or the stem o-ring) fail to work, the seat and stem leakage can be prevented by injecting sealant into these injection fittings, it will be installed on the stem and seat according to the ball valve sizes.
MOST QUALITY Ball Valves FOR YOU
A ball valve is mainly used in the pipeline for shut-off and control applications. It is one kind of quarter-turn valve, it's open when the ball's hole is in line with the flow inlet and closed when it is 90 degrees rotated by the valve handle, blocking the flow. And can usually be lockable at a different position to control the fluid. It's durable, easy operation/repair and has good sealing performance even after a long disuse. All these advantages make it with extensive industrial use like oil&gas, chemicals, pipelines, water treatment, and mining. The ball valve is versatile as there are many different choices of ball valve types available to select according to the working condition.
