Air Preparation Accessories - Blocking Valves
Overview
The blocking valve is a single acting spring return 2/2 valve in a fitting format that provides increased efficiency and productivity within an industrial environment where inspection stops, horizontal indexing or work piece protection is necesary. The device requires a pneumatic pilot signal to open, which allows free flow of air, gas or liquid to pass. As long as a pilot signal is present, the device will remain open. When the pilot signal is removed, the internal spring will close the blocking valve, bubble tight.
The blocking valve is oil serviceable and rated to 150 PSI. These devices have two primary design uses: (1) to prevent unwanted gravity induced motion in cylinders during shut down procedures or during periods of lost supply pressure and (2) freezing the cylinder position by using a blocking valve at each end of the cylinder. Application needs, such as tool or work piece protection, horizontal indexing or inspection stops, are often satisfied by these devices.
