1. Lock bucket valve has pair fraction type, fixed type, metal hard seal type, simple maintenance and convenient disassembly.

2. Double valve seat inlet seal, two valve seats can independently cut off the inlet fluid to achieve double blocking.

3. The integrated design and processing of the ball and the valve stem ensures the neutral and the strength of the valve stem.

4. Inconel X-750 ring spring can maintain the spring stability at high temperature, and the use of unique sealing measures, to ensure that the spring range without ash, to ensure that the seat can float and ball seal.

5. Adopt carbide wideband self-scraping mechanism to realize self-cleaning of spherical surface at the same time of valve opening and closing, to prevent ash from blocking on the sealing surface of the sphere.

6. The use of metal remelting technology will be reliable nickel base carbide and ball, seat matrix surface refusion together, its binding force is significantly better than other ways, can effectively prevent the carbide spalling, falling off; Reasonable hardness difference to ensure that the ball and seat sealing face long life, sealing effect is good.

7. The use of reasonable torque pneumatic actuator and reliable performance of pressure regulating valve, solenoid valve, reversing valve, limit to switch, filter and other gas accessories.
