Adjustable choke valves use a stem and seat combination to control flowrate, by turning a hand wheel to achieve the calibrated orifice size and associated flow coefficient. An easy-to-read indicator allows calibration in 1/64 inch increments.
Positive choke valves provide a fixed flow rate by using a choke bean. Flow rate is controlled by selecting a choke bean orifice size.
Oil & gas wells acidizing, cementing, fracturing, sand control, flowback and well kill.
Choke valves in 2-inch and 3-inch sizes for operating pressures up to 15,000 psi are available.
