The Slab Gate Valves features a non-rising stem with a slab gate,
Full-Bore Thru-Conduit Design, Floating Slab Gate and Seats,
floating seat ring body bushing design to provide safe
dependable service. No special tools are needed to change gate
and seat assembly. The stem pin protects the stem and internal
parts from failure by shearing if the handwheel is over torque.
One-piece gate helps to prevent line sediment from entering the
body cavity and prevents pressure locks when the up stream
pressure drops. A wide range of body and trim materials to meet
various operating conditions.

EXPANDING GATE VALVES
 
The Expanding gate valves provides great
performance to economical applications. The
valve gate geatures simple onepiece 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.  Flanged End
