Series 3B25* and 3B37* Directional Control Valves
The 3B series of 2 position 3 ported directional control valves are available for use on a wide range of media, from gases to sea water and many difficult and hazardous chemicals and fluids. Using a balanced poppet design, actuation of these valves is completely independent from the main line pressures, making switching reliable and consistent. With a vent chamber between the main ports and the pilot system, different pilot and main line fluids may be used without fear of accidental mixing or contamination. Various actuation methods are available, including hydraulic and pneumatic pilots, levers and cams.
