The double-acting throttle, stop and vent valve is a new type of throttle, stop and vent product. The valve adopts cage-type labyrinth throttling, with a multi-stage throttling effect, obvious throttling effect, reliable sealing, and convenient operation and maintenance. It is mainly used in the pipeline of oil, natural gas, and non-corrosive medium transmission system. It can work in an environment of high-pressure difference. It can not only realize throttling and shutoff but also realize the function of pressure-reducing valve
