Air lock relay is used for locking air in both the chambers of cylinders whenever the supply pressure (air Pressure connected to the signal port) falls below the set value. Fluidtecq air lock relays are built very compact to save space. Ideal for precise applications in pneumatic actuators. Fluidtecq air lock relay is installed between solenoid valve, or positioner output & actuator ports. In the event of air pressure failure, the air lock relay maintains pressure lock condition. Air lock relay is highly effective in Holding the air in lock condition, when there is supply failure in the process pneumatic line, thereby keeping the control Valve in stay-put condition. The design is very compact and offers flexibility for panel mounting as well as mounting on Control valves…
