About Series PABR-FSO Air-Actuated Valves

These are air-actuated valves with bi-directional flow. The liquid flow can go from port 1 to 2 and from port 2-1. These valves are anti-waterhammer capable when the water flow goes from port 2 to port 1. This series of air-actuated valves is available from ½" to 2" NPT, and available in bronze.
