1. The bucket lock valve has split type, fixed type and metal hard seal type, which is easy to maintain and disassemble.

2. Double valve seat inlet seal: the two valve seats can cut off the fluid at the inlet end as independently as possible to achieve double blocking.

3. The integrated design and processing of the ball and the valve stem ensure the centricity of the ball and the valve stem and the strength of the valve stem.

4. Inconel X-750 ring spring can keep the elastic force stable under high temperature, and adopts unique sealing measures to ensure that there is no ash in the spring range, to ensure the floating of the valve seat and the sealing of the ball.

5. The wide-band self scraping mechanism of cemented carbide is used to realize the self-cleaning of the spherical surface while the valve is opened and closed, and prevent the ash from blocking the sealing surface of the spherical surface.

6. The metal remelting technology is used to reliably re fuse the nickel based cemented carbide with the surface of the ball and the base body of the valve seat, and its bonding force is obviously superior to other methods, which can effectively prevent the peeling and falling off of cemented carbide; Reasonable hardness difference ensures long service life and good sealing effect of the sealing surface between the ball and the valve seat.

7. Adopt pneumatic actuator with reasonable torque and reliable pressure regulating valve, solenoid valve, reversing valve, limit switch, filter and other air circuit accessories.
