Williams valves are available in double-acting (4-way) or single-acting (3-way) versions. These valves are machined from a solid casting for high-pressure operation. All valves feature ground and chrome-plated spools that are fitted to the bodies by honing. All spools are pressure-balanced for smooth, positive valve actuation. Optional externally-adjustable relief valves are available for working pressures up to 5,000 psig (345 bar). Spool control is three-position spring-centered. Valves may be used in series operation. Flow rating is 6 gpm (22.7 lpm). Port size is 3/8 inch NPT (SAE ORB ports are available upon request). Various spool configurations are available.
