Hannifin has introduced its lever-operated model high-performance directional control valves. The manually operated Vikingxtreme valves are designed to improve productivity in demanding environments, such as those typical of logging equipment, quarrying, commercial vehicles, saw mills and conveyor systems. The Parker Hannifin VikingXtreme valves feature a single piece aluminium spool, over-moulded with a rubber compound, which eliminates seal deformation under pressure. The pneumatic valves offer a variety of different circuit configurations, with both 5:2 and 5:3 functions, including self-centring 5:3 versions. The compact valves incorporate spool technology and have been designed for use in pneumatic systems that have to operate at extreme temperatures, between -40 and 60C, and at pressures of up to 16bar.
