Adjustable Choke Valve

Union-ended adjustable choke for continuous rate and pressure control during fracturing, flowback and manifold service.

PRODUCT OVERVIEW

Purpose and construction

An adjustable choke varies the effective flow area by moving a carbide-lined stem relative to the seat. It provides controllable restriction in temporary high-pressure flowlines and plug-valve choke manifolds while allowing worn trim to be replaced.

Technical features

2 in and 3 in nominal body options
Figure 1502 male × female union connections
3/4 in or 1 in maximum orifice for the 2 in body; 2 in maximum orifice for the 3 in body
Forged alloy-steel body with stainless-steel and tungsten-carbide trim options
Fully lined carbide stem and replaceable service parts
Standard and sour-service configurations

Typical applications

Fracturing and flowback
Wellhead testing and clean-up
Steam or treatment-fluid injection subject to material review
Choke and kill manifolds
Plug-valve choke manifolds
