The expanding gate valve features a non-ring stem with an expanding gate design to provide safe, dependable service in a variety of environments, It’s a available in flanged or threaded ends in standard bore sizes from 2-1/16” thru 4-1/16” in working pressures of 3000psi thru 5000psi.
Full-Bore Design:

Maximizes valve service life.

Eliminates the collections of destructive particles.
Expanding Gate:

Produces a positive mechanical seal across the seats.

Isolates the body cavity from bore pressure in both the open and closed position.
Metal-to-Metal Seal:

Body/bonnet interface, and gate/seat interface.
Press Fit Seat: 

Press fit seats allow the seats to be tightly wedged into the seat pockets in the open or closed position.
Long Life, Low Maintenance:

Simple routine maintenance program limits repairs, eases operation, protects against corrosion, and extends service life.
