A cartridge type control valve for replaceable use in the dispensing head of a fluid dispensing system includes, a fluid transfer assembly having a composite fluid transfer chamber means and an inlet duct assembly made of plastic material, the inlet duct assembly includes a longitudinal leg formed integral with the bottom and sidewall of the fluid transfer chamber means and a transfer leg operatively connected to the longitudinal leg and locked to the sidewall to prevent relative rotation thereof, valve means including a valve stem made of plastic material coacting with a valve port formed in the inlet duct assembly to control flow of fluid through the fluid transfer assembly, and an actuating assembly for operating the valve means with a regulator sub-assembly therein having a valve guide made of plastic material disposed for operative connection to the valve stem. Additionally, the fluid transfer chamber means of the fluid transfer assembly includes, a reinforced cup-like member, an elastomeric diaphragm disposed to lie transversely of the cup-like member to form the fluid transfer chamber therewith, and a cover member, the cup-like member and the cover member having interengaging elements with means thereon to securely clamp the edges of the diaphragm therebetween in assembled position. At least one annular reinforcing element is continuous with the rim of the cup-like member and reinforcing ridges are formed in the bottom or floor of the cup-like member.
