PARKER Hannifin has released PXB-B4 panel-mounted pneumatic valves for applications in manufacturing, mining, processing, metal reduction, packaging, and material handling industries.
Modular construction allows users to mix and match three-ported valves with push buttons and lever actuators. Electrical switches may be piggybacked onto the valves, making the control of pneumatic as well as electrical circuits possible with a single push button or lever actuator. The three-ported valves may be piped for normally closed or normally open operation. Valves and actuators in this range are free of aluminium, an important feature for applications in underground coalmines.
Push buttons are offered with flush, extended, and mushroom heads in spring return and latching types in several colours. Lever operators are offered in two and three position types featuring stay-put or spring centred functions.
The valves and actuators are designed to clip onto each other without the use of tools. Up to three pneumatic valves plus up to three electrical switches can be controlled from a single actuator. The valves are factory lubricated and require no additional lubrication in service.
