piston type flow regulating valve

design features：

1. hollow streamlined valve body, straight through axial symmetrical flow channel, the section is ring; 

2.built-in crank slider mechanism, the valve is fast and then slow, there will be no sudden change of pressure and valve water hammer; 

3.double sealing structure of metal-metal and metal-elastic materials; 

4.the linear relation between the opening and the flow rate can adjust the medium precisely；

5.different types of throttling elements: fan ring type, slot type, multi-jet type, circulation type and other special design, to meet different working conditions.
