Power and Check Valves

SMC

SMC power and check valves control the direction and quantity of airflow in pneumatic systems. The range comprises check valves, quick exhaust valves, throttle check valves in numerous versions and air-saving and safety start valves. More than 1,600 items are listed in this section.

Check valves such as the AK series allow air to pass in one direction only, while throttle check valves additionally set the flow velocity. Versions in stainless steel and for cleanrooms and low-speed cylinders cover special requirements.

Safety Start Valves ASSSafety start valves of the ASS series

Check valve allows air through in one direction only and blocks the reverse direction, such as the AK series.

Throttle check valve sets the speed of pneumatic cylinders via exhaust throttling.

Quick exhaust valve vents the cylinder directly for faster motion.

Safety start valve (ASS) builds up pressure in a controlled manner at start-up.

Power and check valves regulate the travel speed of cylinders, protect compressed-air lines against backflow and control the start-up of systems. Air-saving valves reduce consumption, while special versions address cleanroom and stainless-steel requirements.
