A dual solenoid valve assembly is provided. The assembly includes a casing joined to a housing having a pressure inlet and outlet, an exhaust port, a first fluid path connecting the inlet and the outlet, and a second fluid path intersecting the first fluid path and connected with the exhaust port. A first valve seat is in the first fluid path and a second valve seat is in the second fluid path. A first solenoid coil is mounted within the casing and a first magnetic solenoid stop is mounted within the first coil. A first solenoid plunger is slidably mounted within the first coil biased away from the first valve seat. A first tubular valve stem is fixably connected with the first plunger for sealably contacting the first valve seat. A second solenoid coil is mounted within the casing on a side of the first coil opposite the housing. A second magnetic stop is mounted within the second coil and a second solenoid plunger is biased away from the stop and is slidably mounted within the second coil. A second valve stem is fixably connected with the second plunger. The second valve stem has a head for sealably contacting the second valve seat.

Single ended solenoid valve assembly

A valve assembly having normally opened and normally closed valves controlled by solenoids to provide various connected and disconnected arrangements in a fluid system. It is particularly useful in a wheel lock control or anti-skid brake system (ABS).
