1. Structure of WKM Expanding Gate Valve Description
1) Metal-to-metal sealing (gate-to-seat and seat-to-body).
2) Expanding gate design creates a positive mechanical seal across the seats, with or without line pressure.
3) Full-bore, through-conduit gate-to-seat seal maximizes valve life by virtually eliminating turbulence and pressure drop.
4) Gate skirts reduce loss of body lubricants.
5) Low running stress enhances life of the gate-to-seat interface.
6) Upper/lower roller thrust bearings are isolated from well fluid, minimizing torque.
7) Stem packing can be re-energized with valve under pressure.
8) Non-rising stem permits valve installation in closer quarters.
9) Seats, gates, stem, and other working parts are field replaceable.
