Product Description
Tungsten carbide valve components are critical parts used in severe-service control and isolation valves, where fluid media involves abrasive particles, corrosive chemicals, or high-temperature gases. Retop produces a full range of valve parts such as carbide valve seats, plugs, trims, cages, and discs, all made from cemented tungsten carbide (WC-Co or WC-Ni) with precision grinding, lapping, and coating options to improve sealing, longevity, and resistance to erosion.
These components are essential in choke valves, globe valves, safety relief valves, and control valves operating in oilfield drilling, petrochemical pipelines, high-pressure gas injection systems, power plants, and chemical reactors. Carbide valve parts are also widely used in slurry pipelines, desalination plants, and mining slurry pumps—where traditional metal parts fail prematurely due to erosion, corrosion, or thermal cycling.
Features
Superior Hardness & Erosion Resistance
Handles sand, gas, slurry, and aggressive media under pressure without deformation.Precision Sealing Surfaces
Flatness tolerance < 0.001 mm ensures zero-leak sealing in high-cycle valves.Custom Fit for OEM or API Standards
Supports designs based on API 6A, 6D, and customer-specific geometries.Optional Coatings
Apply TiN, TiAlN, or diamond-like coatings for extended corrosion and wear resistance.Machined to Exact Tolerances
All parts undergo CNC, ID/OD grinding, and ultrasonic inspection.
