At times a driver needs to quickly drop a working rig’s rear suspension, such as to gain more clearance under low openings or when backing under a trailer. Nothing works better for such situations ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.

Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...
