Description

21000 series
The 21000 series single seat valve adopts a top-oriented structure, which can provide enough support to ensure the stable operation of the valve core. The valve has good versatility and can be used for process control of various fluids.
1. Various spools, including quick-change spools, low-capacity spools, soft-seal spools, low-noise and anti-cavitation spools, are widely used.

2. It adopts top guide structure with large guide area and good stability.

3. The leakage is small.

4. The sealing surface of the valve core and valve seat can be surfacing welded with tungsten-chromium-cobalt cemented carbide to improve the service life of the regulating valve.

41000 series

The 41000 series sleeve valve inserts a cylindrical sleeve into the valve body, and is guided by the sleeve, equipped with a spool that slides up and down in it. The sleeve wall has windows with specific flow characteristics. , The valve core moves up and down to change the flow area of the sleeve window hole, thereby achieving the purpose of adjusting the flow rate.

1. The rated flow coefficient is relatively large.

2. The spool adopts a balanced structure, allowing a large pressure difference.

3. The valve core moves in the sleeve, with a large guide area, good shock resistance and wear resistance.

4. Separate the sealing surface and the throttling surface in structure, so that the scouring of the sealing surface is reduced when the medium flows, thereby increasing the service life.

5. Strong adaptability, only need to replace the sleeve to meet different flow coefficients and different

Requirements for flow characteristics.

6. The auxiliary valve core is adopted to achieve a tight seal.

7. Easy to disassemble, inspect and repair.
