Product DescriptionTechnical SpecificationsImage

Adjustable chokes are forged body constructed and designed for reliable flow control and maximum wear life. The variation in choke size is achieved by rotating hand wheel to obtain desired flow rate at downstream side. Tapered annular port is defined by a tapered plug for metering flow of a fluid. The inside of the choke body is vented to atmosphere after the bonnet nut is partially removed. Under critical applications such as gas wells with high pressure drops, abrasive flow and corrosive conditions, the adjustable chokes are used.
