Lancaster Plug and Cage Choke Assembly
Lancaster Plug and Cage Choke Assembly
Product Details
The Plug & Cage Choke offers a vast array of features and options. Operating torque is well below the industry average, making automation simple and efficient.
Unlike many other commodity production chokes, this next-generation design is highly versatile. The body accepts multiple trim profiles, such as a plug/cage, needle/seat, and positive flow bean. Each component is designed to maximize product interchangeability, metallurgy, performance, safety, and automation. This low-torque design was created with automation and PR2 validation in mind.
Applications
Wellhead
FPSO
Process Platforms
High Flow Rate Production
Salt Water Disposal
Water Injection

Lancaster Vector Choke Assembly
The Vector Choke’s patented flow guide is designed to direct incoming flow directly to the orifices of the disc. This eliminates the pile-up of turbulent fluid and particles on the face of the disc. Erosion is a significant problem that other inline disc chokes have not fully solved. Tests and analyses of the Vector Choke have shown significant erosion reduction when adding the flow guide.
The Vector Choke’s orifice design, modeled after the standard Lancaster Plug and Cage Equal Percentage (EP) design, provides precise flow control during operation. The progression of flow area increases nonlinearly, ensuring relative precision at all operation points. The flow rate approximates the EP profile, a unique feature differentiating it from other disc chokes.
The Vector Choke allows low-torque operation up to the maximum working pressure of 10,000 PSI. This is achieved using a worm gear drive, which allows a much smaller, faster-acting actuator to operate the choke assembly.Unlike competing inline chokes, which must be removed for servicing, the Vector Choke can be serviced inline, saving time and resources for your operations.

- Wellhead
- Salt Water Disposal
