The B5 Series valve offers a wide variety of sizes and configurations for general industrial applications. The valve can be installed as a single valve for point-of-use applications or mounted on aluminum bar manifolds for centralized applications. The B5 Series is a fully-featured valve that has multiple solenoid voltages incorporating standard or mobile rated coils. Remote pilot valves are also available. When in service, radial expansion of the spool seal occurs to maintain sealing contact with the valve bore. This sealing method reduces friction and produces a lower required minimum pilot pressure. As the seal wears, it maintains surface contact with the internal bore which reduces valve leakage in high cyclic applications and extends valve life.
