The Expanding gate valves provides great performance to economical applications. The valve gate features simple one-piece design. Seats will be energized by the preloaded-springs or the high pressure vented from upstream, to form a tight seal between seat and gate. The metal-to-metal sealing design is universally reliable in most demanding applications.

The upper/lower roller thrust bearing minimizes operation torque;

Seats may be lubricated from grease injection fitting to reduce abrasion and promote long life;

Non-rising stem design saves installation space;

Stem back seat’s conical seal surface will push against bonnet, stem seal can replaced under pressure.
