Abstract
A flow sequencing valve which employs separate valve elements to generate the force for cycling and to accomplish discharge port sealing is disclosed.The valve may include an integral pilot solenoid for controlling cycling and is characterized by a force generating element, in the form of a variable resistance to flow, which is free to overtravel relative to the port sealing member whereby flow rate compensation is achieved and water hammer effects eliminated.
