Audited Supplier 1. The sealing structure of the valve seat shall be elastic with pre-tightening force, and the upstream and downstream sealing seats shall be sealed at the same time. The valve seat and the sealing object are always face-to-face sealed.
2. The valve seat has a self-cleaning function, and it is not directly washed by airflow during the opening or closing of the flat gate valve. The valve seat shall be made of lubricated and non-abrasive materials.
3. The failure of the valve actuator will not affect other parts of the valve, and the maintenance and replacement can be carried out without disassembling the valve.
4. Yoke sleeve: The aluminum bronze yoke sleeve is equipped with needle thrust bearing to reduce the operating torque.
5. Valve stem: the thread length reaches the bracket; Pin and spot welding; Has stability.
6. Pressure seal: The structure is simple, and it is equipped with segmented retaining rings and silver-plated low-carbon steel washers, which is helpful for disassembly and realization of bonnet seal.
7. Seat ring: The welded seat ring is perpendicular to the flow channel and easy to maintain.
8. Actuator: These valves can be equipped with electric, hydraulic or pneumatic actuators. Standard manual wheels are provided below DN300, and helical gear operating mechanism is provided above DN350.
9. Yoke: The assembled yoke has passed the seismic test and is easy to maintain and install the actuator.
10, gland: two-piece, self-adjusting gland to avoid being ejected.
11. Integral rear seat: hard surface and long service life. Disc: Spring-loaded disc can adjust itself, reducing the torque demand of actuator.
12. Integral stop: integrally cast the bracket stop device to position the assembled bracket disc, making the valve seat more stable and reliable.
