ZhengFeng Valve's top entry ball valves are widely used in oil and natural gas pipelines, oil extraction, refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food and paper making equipment.Installed ball valve in the pipeline disassembly simple and quick, convenient and quick maintenance. When the valve fails in the pipeline and needs to be repaired, it is not necessary to remove the valve from the pipeline, only remove the middle flange bolts and nuts, remove the bonnet and stem assembly from the valve body, and then remove the ball and seat assembly. Repair ball and seat in line. This kind of maintenance saves time and minimizes the loss in production.
Special "V" seat design introduces self adjusting seats into isolation ball valves.This design does not rely on the traditional float valve built-in interference.It automatically compensates for pressure, temperature and wear.As these changes occur, the ball and seat are constantly pressed into the "" V" ", causing the seat to seal and close while using the elastic seat.Maintaining a low pressure seal is the most difficult condition for a ball float valve.The wedge effect on the ball and the seat under the "V" ensures a continuous low pressure seal for the life of the seat.All installed ball valves have an "anti-static" design.All valve configurations also have standard blow-out proof stem.
