• CVC Series

    Our CVCME choke is designed to extend the service life of the choke valve and can significantly outlast the competition. The design utilizes proprietary annulus and trim geometry significantly improving the durability of the choke. In addition, the CVCME takes advantage of Z-6 submicron grade carbide, which combines the highest impact and erosional resistance in the market.

    Our CVCMP choke has similar features and offers all the same benefits as the CVCME, except it has a plug-in-cage design rather than an external sleeve. The CVCMP is for large orifice, low pressure applications and offers very fine control.

    Multistage Trim Design is also available. This includes:

    •  Concentric cage design utilizing internal plug 
    •  Offers multiple pressure drops to counteract flashing and cavitation 
    •  Ideal for service with high pressure differentials 
    •  Significant noise reduction 



    Description

    The CVCME and CVCMP chokes are designed for production christmas trees and manifold service. These chokes can be programmed with algorithims for:

    • Automated wellbore pressure decline
    • Speeding up pipeline pigging
    • Reducing safety valve shutdowns due to pipeline over-pressurization

    Features/Benefits

    • Ultra-low power consumption for solar operation
    • Knife-edge sleeve-over-cage design delivers outstanding performance in sandy/erosive conditions
    • Z-6 sub-micron carbide has highest combination of impact resistance and hardness
    • On-site automation and field service technicians available in most major oil and gas fields to configure wellhead automation; program most RTUs to control the choke, calibrate, and/or troubleshoot
    • Also available in needle/seat, plug-in-cage, or disk-style trim designs
    • PR-2 Tested up to 3" trim
    • Fugitive emissions testing available upon request
