Gas lift flow control valvevs are being made both in-line and angle body configuration with flange, threaded or weld end connections. With a range of trim sizes and materials, these valves use a profiled plug moving into a seat to vary precise flow range thereby providing fine flow control. JVS control valves have become the valve of choice in many gas lift installations.
Features
- Body: in-line or angle
- End connections: flanged, threaded or weld end
- Connections: 1", 2", 3" from ANSI 150# up to API5000
- Trim in stainless steel, hard facing or tungsten carbide
- Profiled trim to provide linear characteristics
- Adjusting handle to provide contrinuous control
- Indicator barrel shows valve setting in 1/64"
- Valves can be automated with electric or pneumatic actuators
- Custom engineered microspline trims provide control below Cv_0.01 and maybe interchanged in standard bodies
