The stagnant medium in the valve chamber due to temperature changes and abnormal boost, the medium pressure to push the seat out of the sphere, to achieve the effect of automatic pressure relief, the seat automatically reset after pressure relief.

Hard seal ball valve, manual cast steel hard seal ball valve body surface adopts advanced spraying technology, through the treatment of different working conditions, the highest hardness can reach HRC78. Seat sealing faces are handled for maximum hardness up to HRC72. The BALL AND SEAT ARE GROUND IN pairs, and ALL sealing areas of the entire sealing face of the ball valve are precision ground.

Track BALL valve according to the structure of the form can be divided: A floating ball valve: ball ball is floating, under the medium pressure, the ball can produce a certain displacement and tight pressure on the export end of the sealing surface, to ensure that the export end of the seal. Floating ball valve structure is simple, good sealing, but the ball to bear the load of the working medium all to the outlet sealing ring

The natural gas ball valve is equipped with pneumatic actuators. The speed of the pneumatic actuator is relatively fast, the fastest switching speed of 0.05 seconds/time, so it is usually called the pneumatic quick cut off ball valve. Pneumatic ball valves are usually with various accessories, such as solenoid valve, air source treatment sanlian pieces, limit switch, locator, control box, etc., in order to realize the local control and remote centralized control, in the control room can control the switch of the valve, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety.
