Abstract
A split body, rotary C gate, removeable stem vacuum valve using an input assembly with handle extensions that allow for hand movement of the incoming pipe to access an inner aperture body with a curved sealing face that directly seals to a C shaped gasketless gate that can be rotated into and out of the inner body aperture for easy cleaning. The gasketless gate is held in position using gate axles with an outer axle stem connected to a polygon lower body that mates into a matching polygon aperture on the gasketless gate. The middle valve assembly's gasketless housing body defines upper and lower axle washer pockets for locating the axles for proper operation and simple axle pins for securing the axles in position.
