PNEUMATIC VALVE
A Hand Lever Valve 1/4" × 5/2 is a type of manually operated directional control valve used mainly in pneumatic systems (compressed air circuits). This means the valve is operated manually using a lever. When you push or pull the lever, it changes the airflow direction. Refers to the size of the inlet and outlet ports (usually 1/4 inch BSP or NPT threads). This determines how much air can flow through the valve and what piping it connects to.
