Tungsten Carbide Cage for Choke Valves

Retop produces precision-engineered tungsten carbide cages designed for severe-service choke valves. These components ensure flow control accuracy, extended wear life, and stability under high-pressure and high-velocity fluid conditions.

Product Description

Carbide cages for choke valves are precision flow-control components manufactured from cemented tungsten carbide. These cylindrical cages contain metering orifices and control slots that regulate fluid or gas flow within severe-service environments. Retop’s carbide cages are sintered for hardness, CNC-machined for dimensional accuracy, and often paired with carbide plugs or trims for complete valve assemblies.

These cages are widely used in oil & gas wellheads, drilling mud lines, fracking systems, and high-pressure injection choke valves. They offer reliable performance in environments involving sand-laden flows, gas-liquid mixtures, corrosive media, and rapid pressure drops. Ideal for API 6A and custom choke valve configurations used in offshore rigs, shale gas, petrochemical pipelines, and high-erosion process systems.
