Parker has launched a new range of pneumatic solenoid valves, designed for use in extreme conditions. Called Viking Xtreme, the new valves incorporate spool technology and have been developed for use in applications where pneumatics systems have to operate at extreme temperatures, as low as -40C, and at pressures of up to 16bar. The new Viking Xtreme valves feature a single piece aluminium spool, over-moulded with a specially formulated rubber compound. This eliminates the problems of seals deforming or extruding especially under conditions of high pressure or flow. As a result, the new Viking Xtreme valves can be used in higher pressure, high flow applications, and offer low levels of spool break-away force or sticktion, allowing fast change-over even at low operating pressures. The high pressure capabilities of the new valves construction, enable them to be used in applications that include logging and construction equipment, quarrying and in sawmills or paper and pulp mills.
The new Viking Xtreme is available in four versions, with 0.125, 0.25, 0.375 and 0.5in ports.
