Flow Control, Check & Exhaust Valves
Valves that set speed, stop backflow and release air quickly. Items include flow control valves, needle valves, check valves, pneumatic non-return valves and quick exhaust valves. Fine tuning of speed and direction in a circuit is often done with these small, low cost parts.
They are fitted close to cylinders and in air lines to tune actuator speed or keep pressure from draining away. Consider the port thread, the direction of flow control, the adjustment style and the medium.
- Setting cylinder speed in air circuits
- Preventing backflow in supply lines
- Venting cylinders for faster return strokes
