Mud Gate Valve manufacturer in USA

SVR Global manufactures mud gate valves that are specifically designed to manage solids, abrasives, and pressure in drilling, mining, dredging, and mineral processing applications in the entire United States. The valves are manufactured using a full port bore, bidirectional seal, and bolted bonnet construction to avoid clogging and wear at the valve seats.

What is a Mud Gate Valve?

The mud gate valve is a type of robust, wedge gate valve or knife gate valve that is used for isolation and controlling the flow of drilling fluids, slurries, abrasives, and other solid material filled slurries in high solids concentration pipelines. While normal gate valves have no such features, the mud gate valve has a highly durable gate mechanism which is not easily worn out due to suspended solids.

Core Design Attributes:

Full bore, unobstructed flow path to prevent solids build-up
Flat, wedge shaped or parallel gate for positive shut-off against abrasive media
Bolted bonnet construction for field maintenance and gate replacement
Rising stem and non-rising stem configurations available
Metal seated and resilient seated options for varying service conditions
Flanged, buttweld, or hub end connections per pipeline specification
Rated for mud pump discharge lines, standpipe manifolds, and choke lines

Materials of Construction:

SVR Global fabricates mud gate valves in a range of alloys selected for abrasion resistance, sour-service compatibility, and pressure containment:

Cast steel (WCB, WCC) for standard drilling and slurry service
Cast stainless steel (CF8M, CF3M) for corrosive fluid handling
Duplex and super duplex stainless steel for high chloride environments
Alloy 20, Hastelloy, and Monel for aggressive chemical media
Hardfaced gate and seat surfaces (Stellite overlay) for extended wear life
NACE MR0175 / MR0103 compliant trims for sour gas and H2S service

Pressure Classes and End Connections:

ANSI/ASME Class 150 through Class 2500
API 6A working pressure ratings for wellhead and choke manifold service
Flanged ends per ASME B16.5 / B16.47
Buttweld ends per ASME B16.25
Hub connections per API 6A for wellhead stack integration
Face to face dimensions per API 6D and ASME B16.10

Standards and Certifications:

API 6A for wellhead and drilling equipment
API 600 / API 603 for cast gate valve design
ASME B16.34 pressure temperature ratings
NACE MR0175 sour service compliance
ISO 9001 manufacturing quality management
