Abstract: A filler spool valve is disclosed having an open ended housing with an elongated cylindrical passage therethrough. A valve core having a plurality of evenly spaced arcuate and inline passages is reciprocated by a pneumatic cylinder connected thereto by a quick connect coupling to alternately cause a flowable product to flow along generally C-shaped passages, and thereafter linear passages, in the spool valve in response to reciprocation of the valve core. The valve core is easily removed from its housing for cleaning by opening a quick release coupling and manually pulling the core from the cylindrical housing.
