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.
