Product: GAY42X Direct acting piston type pressure reducing valve.
Pressure Rating: 1.0- 6.4***
Specification: DN20-400
Material: Steel, CF8
Standard flanges: DIN, ANSI, JIS;
Structural Characteristic&Purpose.
This series pressure reducing valve is a new type regulating valve which adopts piston to replace the diaphragm. The performance is reliable and it's can be used for a long time. The down pressure can be adjusted according to the requirement, and it can be set at a fixed pressure in the application, which won't be changed as the fluctuation of the up pressure and the flowing rate.
