Description
The R-5-1/4-B Roller Lever Valve is a compact pneumatic directional control valve designed for industrial automation applications. This valve features a roller lever actuator that is mechanically operated by cams, machine parts, or workpieces, making it ideal for position detection and signal initiation in pneumatic circuits. The “R-5” series is known for its robust construction and reliable performance in demanding environments, while the “1/4-B” designation indicates a 1/4-inch BSP (British Standard Pipe) port size. It is commonly used in packaging machinery, material handling systems, and assembly automation.
