PBN Series follows the same body, port and pressure platform in a normally-closed-only configuration for dedicated shut-off duty.
PCN and PBN valves use the same coil options as the rest of the UFlow diaphragm and direct-acting range.
Water treatment mains, LPG and process gas lines, chemical transfer, and any large-bore utility line needing solenoid-actuated on/off control.
