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.
