Pneumatic Blocking Valves.
Blocking valves are a 2/2 way pilot operated valve which can be directly port mounted to cylinders and other devices. The blocking valve requires a pneumatic pilot signal to open which allows air flow to the coupled device. Upon removal of air to the pilot control, the blocking valve can either be totally blocked (two way) allowing no air to pass through the valve, or can allow air to pass in one direction only (one way), see ordering information for further details.
Port sizes are G1/8, G1/4, G3/8 and G1/2 female to male threaded.
