ABSTRACT:
A four-way fluid valve combines direct solenoid operation of one port with pilot valve operation of a second port and a common exhaust port, all of the ports being located in the valve body. Direct valve operation is achieved by a magnetically operated plunger carrying a normally closed valve element and operable to move a separate valve holder carrying a normally open valve element. A pilot operated valve disc is supported at the inlet port for axial movement to inlet or exhaust positions in response to inlet pressure or a pilot-operated piston.
