High performance long life pneumatic solution
Parker Hannifin has developed an air piloted pneumatic solution for its Viking Lite Range. This addition allows the performing range of value engineered directional control valves to be specified in applications where air pilot is required.
The Viking Lite series offers a choice of three port sizes, G1/8, G1/4 and G3/8, in a compact design with direct body porting and integral mounting holes for a solution that can be used in a range of industrial applications.
Robust performance and long service life are offered through Parker's Wear Compensation System. Fitted with bi-directional spool seals, the range is said to operate comfortably at pressure up to 10 bar and in ambient temperatures from -10 to 50ºC and is able to deliver 10 million operating cycles.
In addition to single valve installation, Viking Lite gives designers the flexibility to install the valves in two ways; a manifold bar installation with common ducts for ports 1, 3 and 5, with space for between 2 and 14 valves, or a pressure bar installation for common primary air supply. When pressure bars are used, restrictor-silencers can be installed in the exhaust ports of each valve, for individual adjustment of cylinder or air motor speed. Pressure bars are available in a number of different sizes, with space ranging from 2 to 10 valves.
