| | China Fully Welded Ball Valve (17th Aug 23 at 3:08am UTC) | | China Fully Welded Ball Valve
GZP Pipeline Ball Valves are manufactured to the latest edition of API 6D and tested to API 6D. Passed API 607 fire test standard for soft seal valves. All valves from GZP VALVE are strictly 100%tested before shipment to guarantee zero leakage.
API Pipeline Ball valve are used for fluid regulation and control, usually used as an emergency cut-off, higher safety and operational reliability are required when accidents and disasters occur. They are widely applied in petroleum refining, long pipeline systems, nature gas, power, metallurgy, energy systems, gas chemical etc.
Ball valve is the valve that the stem drives the ball to rotate around the axis of the ball valve, it can be closed with 90degree rotation in a very little torque, and ball valve has a good sealing performance, light switch and long service life.
The main construction features of GZP Pipeline Ball valve are following:
1. Body锛?PC, 2PC, 3PC and welded
2. Port: Full bore and Reduced bore
3. Ball Type锛欶loating ball and fixed ball
4. Sealing Type: front 鈥搒eat sealing, Back-seat, bi-directional seal
5. Sealing:Multi-Sealing Design
Except primary sealing, GZP pipeline ball valve has secondary seal design to play an emergency rescue role when the sealing is damaged or leaked. The fire safe design can form a metal-to-mental seat in case of the sealing ring is burned by fire to effectively prevent the spread of media and fire.
6. Fire safe and anti-static design
A conductive spring is designed between the ball and stem,stem and body,so the static energy can be introduced to the ground through the electrostatic channel to achieve the purpose of removing static electricity. Avoid static ignition of flammable media ensures system safety.
7. Blowout-proof stem, automatic pressure relief design, emergency grease injection design, drain valve, locking device, anti-corrosion design, anti-sulfur design etc
The stem adopts the bottom-mounting design so that the stem will not be blown out by the high-pressure medium even the valve body's abnormal pressure rise and invalid packing gland;
The packing designs a reasonably V-shaped structure, which can effectively convert the medium pressure of inside body cavity and the locking force of the external gland into the sealing force of the valve stem.
When the stagnant medium increases pressure abnormally due to temperature changes, the medium pressure will push the valve seat away from the ball to achieve the effect of automatic pressure relief and after pressure relief, the valve seat can automatically reset
Drain valve designs to check whether the seat is leaking and discharge the retentate from the body cavity to reduce the pollution from medium.
