Features: Usage scenarios: air compressors, pneumatic tools, gas connection installation, effective filtration of air moisture. Use to control the pressure element and the backlog. It uses the intake throttle pressure, by the force balance and overflow regulator. To change the gas line pressure, first pull out the hand wheel, and then to get any pressure within the specified range through mediation plastic handwheel. Clockwise to increase pressure and anticlockwise reduce pressure.
