Tungsten Carbide Coating Mud Valve Gate with Anti Erosion
Product Description
Crafted from high-strength alloy steel (42CrMo, 17-4PH) or wear-resistant stainless steel as the base material, the product undergoes quenching and tempering heat treatment to enhance overall rigidity and impact resistance. The working surface is processed with HVOF (High Velocity Oxygen Fuel) spraying technology or tungsten carbide (WC) overlay welding, forming a dense, high-hardness protective layer with strong bonding force. With precision CNC machining, the valve gate features accurate dimensional tolerance, flat surface, and tight fit with the valve seat, achieving reliable sealing and smooth flow control without leakage.
Ideal for high-pressure, high-wear, and corrosive working conditions, this mud valve gate effectively resists particle abrasion, medium scouring, and chemical corrosion, significantly reducing maintenance frequency and replacement costs. It is widely applied in oilfield drilling rigs, mud circulation systems, slurry pipelines, and other heavy-duty scenarios, becoming an indispensable key accessory for mud valve systems.

Product Features
HVOF spraying/tungsten carbide coating provides exceptional wear resistance, resisting scouring from high-solid-content mud and extending service life by 3-5 times compared to ordinary valve gates.
Quenched and tempered base material with high tensile strength (≥ 1000MPa) ensures stable operation under high-pressure conditions (up to 105MPa) without deformation or cracking.
Precision CNC machining ensures flat sealing surface and tight fit with the valve seat, effectively preventing mud leakage and ensuring flow control accuracy.
Wear-resistant alloy base material + anti-corrosion coating resists corrosion from acidic/alkaline mud and chemical media, adapting to complex working environments.
Suitable for oilfield drilling, mud pumps, slurry transportation, and other heavy-duty scenarios; supports customization of size, material, and surface treatment per customer requirements.
