Key wear-resistant throttling components for severe service
Our Choke Valve Cages are designed for severe service applications where erosion resistance, dimensional stability, and flow-path accuracy are critical. Suitable for choke valves, wellhead equipment, Christmas tree systems, flowback units, and high-pressure process control assemblies.
Choke Valve Cages are key wear-resistant throttling components used in high differential pressure, high flow velocity, solid particle-containing, and erosion-prone media control systems.
Manufacturing & Quality Control
We manufacture choke valve cages through controlled powder processing, pressing, vacuum sintering, optional HIP densification, and precision machining.
- Dimensional consistency for multiple orifices and labyrinth flow paths
- Sintering shrinkage compensation for thin-wall areas
- Orifice edge integrity and surface roughness control
- Control of cracks, edge chipping, and hidden defects
- Assembly matching control with valve cores and seats
Selection Recommendations
Choose the right cage for your application:
- **High sand content and high differential pressure**: prioritize high wear-resistant grades
- **CO2, H2S, or corrosive media**: comprehensively evaluate binder phase system
- **Cavitation or flashing risks**: prioritize multi-stage pressure reduction or labyrinth structures
