Parker PWB-A1483 Blocking Valve

The Parker PWB-A1483 Blocking Valve is a shutoff component with a 3/8 in BSPP connection and ports available in 8 mm and M5x0.8 threads, rated for service up to 150 psi. It blocks flow in a line to allow maintenance or isolation in hydraulic or pneumatic circuits, using compatible BSPP and metric/M5 fittings as specified by the port options. The PWB-A1483 designation identifies Parker’s blocking valve series and helps ensure correct mating with Parker components and applicable adapters for the listed port sizes. This valve configuration supports installation in systems where space is limited and multiple port types are required, providing a straightforward means to stop flow without removing other line hardware.
