Product Description

 

Overview

This valve uses triple eccentric configuration with laminated metal seat to apply in wide sectors, such as power plant, oil & gas, petrochemical, water drainage. 


Features
 

1. Laminated metal and graphite seat in disc boosts the superior performance in extreme conditions;
2. Triple eccentric structure frees the valve from abrasion and friction between seat and disc when the valve closes;
3. The seat of body can be overlaid with hard alloy to endure over 100000 times of cycling life; 
4. Bi-directional performance can be achieved after our optimization.
