Description

Design Features:
1、Meet the requirements of advanced standards, reliable sealing, excellent performance and beautiful appearance.
2、The sealing matching is advanced and reasonable. The sealing surface of the gate and the valve seat is made of hard alloy with different hardness. The sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long life.
3、After quenching and tempering and surface nitriding treatment, the valve stem has good
corrosion resistance, scratch resistance and wear resistance.
4、Various piping flange standards and flange sealing surface forms can be used to meet various engineering needs and user requirements.
ZG valve has obvious advantages such as light switch, reliable sealing, good elastic memory and service life.

Field of Application:
Size Range: DN40 and DN300
Temperature: （-）29℃ to 425℃
Allowable Operating Pressure:PN16、PN25、PN40
Gate valve is widely used in petrochemical plants, metallurgy, water treatment, thermal power plants and other oil and water vapor pipelines to connect or cut off the medium in the pipeline.
