DRU non-adjustable angular throttle valves

The non-adjustable angular throttle valve is designed for step control of the mode of operation of the oil and gas wells. It is used when it is necessary to perform step control of the fluid flow-rate in the flow head equipment at wellhead, blowout preventer equipment, trunk pipelines and pump units.

The working medium flow control is performed by replacement of the nipple inserts having different flow areas.
