ABSTRACT:
A multi-position valve for dispensing fluid and providing continuous fluid flow through the valve assembly. The multi-position valve assembly including an inlet port, an outlet port, and a return port leading to a fluid chamber. The multi-position valve assembly further includes a closure assembly for selectively directing fluid through the valve assembly. The closure assembly is operatively connected with some type of linear actuator, such as an air cylinder, for selectively moving the closure assembly and placing the multi-valve assembly between a closed position, a partially-open position, and a fully-open position. When in the closed position, the closure assembly directs fluid flow through a return flow path leading to the return port, while blocking the fluid flow to the outlet port. When in the partially-open position, the closure assembly directs fluid flow through both the return flow path and a first outlet flow path leading to the outlet port. When in the fully-open position, the closure assembly directs fluid flow through both a first and a second outlet flow path leading to the outlet port, while blocking fluid flow to the return port. The air cylinder is detachably connected to the valve to provide for repair and replacement.
