The Model SG-22 high-performance, bidirectional slab gate valve is ideal for high pressure, critical serice applications 2,000 through 20,000 psi on welleads, production trees and manifolds.
► Incorporates a non-rising stem to provide safe, dependable service in a variety of environments.
► The full-bore through conduit design maximizes the valve life and virtually eliminates turbulence and pressure drop across the valve.
► The slab gate creates a positive seal across the seats with the use of line pressure.
► One-piece seat provides a metal-to-metal seal against both the gate and the valve body without elastomeric seal backups.
► Threaded bearing cap allows for replacement of the bearings or the stem pin while the valve is under pressure.
► Self-energizing stem packing for minimal maintenance.
► Metal-to-metal stem backseat provides maximum safety in case of stem packing leak and allows for body pressure containment in the instance of packing leakage or body lubrication fitting damage.
