A charge valve assembly for an air conditioning system includes a valve housing having a first end, a second end, and an inner surface defining a cavity. A valve core assembly is received in the cavity of the valve housing through the second end of the valve housing. The valve core assembly has a first end, a second end, a flow channel extending from the first end of the valve core assembly to the second end of the valve core assembly, an inner sealing surface, and a pin slideably received in the flow channel between an open position and a closed position. The pin has a primary seal selectively engaging the inner sealing surface of the valve core assembly and closing the flow channel at the second end of the valve core assembly when in the closed position. The pin biases towards the first end of the valve housing.

A valve assembly with at least two valve modules is described, wherein the valve modules are arranged one beside the other in a line-up direction. The valve assembly also comprises an indicating device for displaying a state of the valve modules and/or of the valve assembly and/or of a component connected to the valve assembly. In the line-up direction the indicating device continuously extends over all valve modules.

A valve core includes: a barrel part that is cylindrical; a barrel packing that surrounds an outer lateral surface of the barrel part; a washer through which the barrel part penetrates and which abuts on the barrel packing from above; and a head part that includes a male screw part at its outer lateral surface and that rotates relative to the barrel part, wherein a lower surface of the head part abuts on the washer from above.

In order to solve the problem, a valve core according to one aspect of the present disclosure including: a barrel part that is cylindrical; a barrel packing that surrounds an outer lateral surface of the barrel part; a flange part that abuts on the barrel packing from above; and a head part that includes a male screw part at its outer lateral surface and that rotates relative to the barrel part. A lower surface of the head part abuts on the flange part from above.

A valve cartridge assembly supported by a receiver and fluidly coupled to a waterway assembly. The waterway assembly includes a base and a plurality of flexible tubular members. A gasket is received intermediate the receiver and the waterway assembly.
