Neway expanding gate valves are widely applied where high performance is required like in high temperature and high pressure pipelines. Neway's expanding gate valves are 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.
