Product Overview
High temperature and high pressure ball valves have a metal sealing structure, and the sealing form is metal to metal sealing. The metal sealing ring can be exchanged for metal sealing, and the stainless steel plate and graphite composite plate sealing ring can be used for metal sealing. The driving forms of hard sealed butterfly valves include manual, worm gear drive, pneumatic, etc. in addition to electric. The butterfly plate of the high-temperature ball valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the hard sealed ball valve body, the disc shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When the rotation reaches 90 °, the valve is fully open.
Structural characteristics
1. When the ball valve is fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.
2. The ball valve has a simple structure, good sealing performance, and small opening and closing torque.
3. Has a low flow resistance (actually close to zero).
4. Reduced or full diameter.
5. Flange end face or butt welded end face.
6. Soft sealed ball valves are equipped with fire and anti-static devices.
7. The valve stem is designed to prevent spray, which can prevent the valve stem from spraying out of the valve body due to improper operation.
8. A connecting plate that can be matched with various driving devices. The driving device includes a handle, worm gear, electric, pneumatic, gas-liquid linkage, electro-hydraulic linkage, etc.
9. Convenient position adjustment. When replacing or installing the actuator online, the position of the ball hole cannot be clearly seen. BTL ball valves provide a special "positioning groove", which can easily and accurately find the fully open and closed position of the ball valve. Convenient adjustment of the actuator limit device.
10. For valves with welded ends, the end material (transition section) of the valve can be adjusted according to the user's pipeline material level response to ensure the adaptability and weldability of the material strength. The valve with sleeves added at both ends ensures that the length of the sleeves does not affect the sealing material during on-site welding operations.
11. Buried design. Valves installed underground, with valve stems extended according to engineering needs for ground operation, and corresponding grease injection, drainage, and venting devices extended from pipes to the ground.
