It is suitable for general working media such as water, solvent, acid and natural gas, and the high temperature and high pressure ball valve is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and is widely used in various industries. The high temperature and high pressure ball valve body can be integral or combined. The sealing ring is composed of multi-layer stainless steel sheets on both sides of the soft T-shaped, which has the dual advantages of metal hard sealing and soft sealing.

No matter in low temperature or high temperature, the high temperature and high pressure ball valve has zero leakage sealing performance. The test proves that when the pool is in a positive flow state (the direction of medium flow is the same as the direction of rotation of the butterfly plate), the pressure on the sealing surface of the high temperature and high pressure ball valve is generated by the torque of the transmission device and the action of the medium pressure on the valve plate. When the positive medium pressure increases, the tighter the oblique conical surface of the valve plate and the sealing Butterfly Valve surface of the valve seat are, the better the sealing effect will be.
