产品介绍

Feature

1.This valve is suitable forANSI Class 150~2500

It adapt to the pipeline of petroleum, chemicalindustry and fire power station. The main function of this valve is to cut andconnect the medium in the pipeline.

Operating temperature: -29~570

Applicable medium: water, oil, steam, acid, etc.

Operation mode: manual, gear drive, electric, etc 

2.The seal contact face of disc and valve seat wasbead welded by Iron-based alloy or cobalt-based alloy which has the advantagesof high hardness, wear resistance, high temperature resistance, corrosionresistance, good abrasion resistance and long service life.

3.The Stem has good corrosion resistance and abrasionresistance because of the conditioning and surface nitrificationmethods

4.Theproducing progress was controlled by ANSIB16.34, so it can be directly used to import equipment. 

5.The opening and closing of electric valve wascontrolled by the electric actuator

Our electric actuator has special motor, reducer,torque control mechanism, operating mechanism, hand electric switchingmechanism. In this way, it can realize remote operation.
