About Parker Hannifin B31VBB557C Series B3 Pneumatic
Description The B3 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 B3 Series is a fully-featured valve that has multiple solenoid voltages incorporating standard or mobile rated coils. Remote pilot valves are also available. The B3 Series valve is a basic 1/8" ported valve. The bi-directional wear compensated spool performs well in temperature ranges from 5F to 120F and pressure ranges from Vacuum to 145 PSG. 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.
