Product Description

API 6A "DEMCO" Mud Gate Valve Casting Body Mud Valve with High Pressure

 

Product Description

The Mud Gate Valve, with superior design features precision workmanship and a proven principle are engineered to meet the harsh drilling requirements in today's oilfield.

The Valve standard trim includes 316SS Gates 316SS Stems and Buna N seats, optional trims are available which include Ni Plated Carbon Steel, Monel and Aluminum Bronze gates. Seats are offered in Viton and Hypalon and optional 303SS Stem is available.

 

Construction

All the Valves conform to API flange dimensions in all pressure class ratings. The valves have rising stems that are driven by a double threaded hub for quick opening and closing with minimum turning effort. The permanently lubricated stems and stem screws are fully sealed assembly consisting of homogenous and fabric backed rings for high and low pressure sealings.

 

Application for the Gate Valve

Mud pump lines and Standpipe manifolds, Oil and gas pipelines, Sour gas and crude oil, Corrosive water flood lines, Cementing services, Wellheads, Well treating chemicals.

SLAB GATE VALVES



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
