Tungsten Carbide Coated Solid Mud Valve Gate | API Standard Oilfield Drilling Valve Trim
Product Description
The mud valve gate (solid wedge) is the core internal trim component of drilling mud valve, widely used in oil & gas drilling mud manifold, mud circulation system, high-pressure fluid control wellhead equipment. It serves as the opening & closing sealing part to cut off or conduct drilling mud, slurry and high-pressure corrosive fluid. Our products are strictly produced per API specifications, equipped with HVOF tungsten carbide coating on sealing surface, outstanding anti-abrasion & anti-erosion performance for harsh drilling environments.
Product Features
- Integral Solid Wedge Structure One-piece forging & machining molding, high structural rigidity, no deformation under continuous high-pressure mud impact; stable sealing performance, no leakage during frequent switch operations.
- Supersonic Tungsten Carbide Sprayed Sealing Surface Our core process: HVOF WC coating greatly improves resistance to mud particle erosion, abrasion and slurry corrosion. Service life is 3~5 times longer than ordinary nitriding / hard chrome plating gates, effectively reducing valve spare part replacement frequency and downtime cost for drilling rigs.
- Strict API 6A Standard Compliance All raw material smelting, precision machining, surface treatment and inspection procedures follow API 6A oilfield specifications, can pass third-party inspection, meet global oil & gas company procurement certification requirements.
- Strong Medium Adaptability Applicable to water-based mud, oil-based mud, solid particle-containing drilling slurry, high-pressure saltwater and slightly acidic corrosive media; works stably in cold & high-temperature field environments.
- Customization Supported We can customize gate size, base material, coating thickness, hardness and machining tolerance according to customers’ drawings, samples and special working condition demands.
- Precision Machining & Stable Tolerance Strictly control fillet, edge, thread and overall dimensional tolerance; interchangeable with original brand OEM spare parts, convenient for on-site maintenance replacement.
