API 6D Parallel Expanding Gate Valve , Inch2"-24" , Class300 - 2500 Carbon Steel, Stainless Steel
Zaval expanding gate valves are widely applied where high performance is required like in high temperature and high pressure pipelines. The design is in compliance with API6D and provide a superior bi-directional torque based mechanical seal. During operation the gate assembly travels freely between the seal surfaces which will reduce the wear risk and prolong the valve service life.
