Product Introduction
Expanding gate valves are widely applied where high performance is required like in high temperature and pressure pipelines. The expanding gate valves comply 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.

Features
Expanding gate design is versatile in that it provides a mechanical seal between the seats and the gate ensuring valve integrity at both high and low line pressure. The expanding gate valve does not reply on line pressure to seal and is recommended for applications when a tight mechanical seal is required.
