A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A plurality of discharge seals may be provide between the outer valve member and the inner valve member, with one of the discharge seals extending around openings of the outer valve member or openings of the inner valve member. A first circumferential seal may also be provided. An engagement structure including a plurality of spaced apart vertical engagement projections and a plurality of complementary configured engagement recesses may be provided between the valve assembly and the base. A locking arm having a locking member may be provided with the locking member positioned in a locking receptacle. A projection engages the locking arm to move the locking member from the locking receptacle.

Material supply system with valve assembly

A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A base assembly includes an base structure and an actuator. An engagement structure is operative between the outer valve member and the actuator to prevent relative movement between the outer valve member and the actuator. A locking structure is operative between the inner valve member and the base structure to prevent relative movement between the inner valve member and the base structure. Movement of the actuator relative to the base structure moves the outer valve member relative to the inner valve member to operate the valve assembly.

A closed loop dispensing system comprises a connector connectable to a container for selectively dispensing the fluids from the container. The connector includes an outer cap having a first passage with an interior surface. The first passage can have variable cross-sectional areas over different regions of the first passage. The connector comprises a plug slidingly movable between an open position and a closed position, wherein, the plug allows passage of fluids present in the container in the open position, and the plug prevents passage of fluids out of the container in the closed position. The plug can have a variable cross-sectional area thereby preventing the plug from being disengaged with the outer cap or sliding out of the connector and into the container.
