Features And Benefits
The top-entry ball valve is designed as a one-piece valve with the support plate and ball secured to a top-mounted, integrated pivot, which tightens the ball in position by the combined force of the pivot and the support plate.The unique retractable seat enables in-line replacement of the valve stem, stem gasket, metal seat, and spring.
Standards And Specifications
The ball valves are designed according to ISO14313, API 6D, BS 5351 and GB/T 19672 standards for oil, gas and chemical industries to ensure safety and reliability.
Structure And Sealing
Simple structure, excellent sealing performance, low operating torque, suitable for high pressure and high temperature working conditions, easy to operate and maintain.
One-piece Valve Body
Adopt one-piece valve body design, reduce leakage points, stable structure and long service life.
Low Flow Resistance
Reduction and through-diameter structure design, low flow resistance, through-diameter design under the flow resistance is almost zero, improve the conveying efficiency.
Emergency Oil Filling
Equipped with emergency oil filling function, the seal can be quickly repaired in emergency situations to ensure stable operation.
Automatic Pressure Relief
The automatic pressure relief function in the center chamber prevents overpressure and improves the safety of the piping system.
Low Leakage Packing
Low leakage packing is used to prevent fluid leakage, especially for high pressure conditions, ensuring environmental protection and safety.
Multi-protection
Equipped with fire protection, anti-static and anti-stem washout designs to improve overall safety.
Valve Seat Function
Support double block double row, single side piston, double side piston multiple functions to meet different sealing needs.
Extended Stem And Bonnet
Valve stem and bonnet can be lengthened to adapt to underground or special environments, increasing the convenience and protection of operation.
