A non-riser valve assembly 30 includes a bonnet or housing 32, a bushing 34, a stem 36, a washer 38 and a stop 40. The assembly 30 further includes a coupling 42, a rotatable or movable disk 44, a fixed disk 46 and a bottom seal 48. In assembly, the bushing 34 and the stem 36 are located within an opening 50 of the housing 32 with the bushing being located between the housing and the stem. One of the stem 36 extends from one end of the opening 50 and the stop 40 is removably attached to the stem to limit the rotational movement of the stem within the housing. The coupling 42 is located in the opening 50 of the housing 32 and is in driving engagement with the opposite end of the stem 36. The movable disk 44 is located with the opening 50 and is coupled to the coupling 42 for rotation therewith. The fixed disk 46 is attached to the housing 32 within the opening 50 and is formed with a surface 224 which is in water-sealing engagement with a surface 162 of the movable disk 44. The disks 44 and 46 are formed with passages 164 and 218, respectively, the relative positioning of which is controlled by rotation of the stem 36 to control the flow of water therethrough.

Valve assembly

A faucet system includes a cold water control valve and a hot water control valve. These control valves are in communication with each other through a cold water supply conduit and a mixed water conduit. The hot water control valve includes a needle valve and a valve seat. The needle valve is adjustable with respect to the valve seat to adjust the maximum temperature of hot water being supplied by the hot water control valve to the mixed water conduit. In one embodiment, the hot water control valve of the faucet system further includes a pressure balancer disposed between the hot and cold water supply and the hot and cold control valves.

Anti-scald faucet system

A pressure balancer system 10 having a pressure balancer 20 and a temperature controller 24 on one side of the system and a volume controller 14 on the other side of the system. The pressure balancer 20 receives hot and cold water which it discharges into the temperature controller 24 at substantially constant preselected pressure. The temperature controller 24 is adjustable to set the temperature of the flow to keep the temperature of the anti-scald below the maximum temperature of between 115.degree. F. and 120.degree. F. The volume controller received the temperature adjusted flow from the temperature controller and will set the volume of the flow at the desired volume for discharge therefrom.

2/3 handle pressure balancer system

A check valve 10 for a fluid passageway 12 or 14 of a pressure balancer 16 or the like, and having a base plate 40 with an opening 62 therethrough connected in the passageway 12 or 14. The underside 42 of the base plate 40 disposed in the passageway 12 or 14 to face normal flow therein and the upperside 44 facing the opposite direction. A substantially 'U' shaped frame member 79 is connected on the upperside 44 of the base plate 40. The frame member 79 carries two leg members 52 and 54 extending from the upperside 44 of the base plate 40 on opposite sides of the opening 62 with a bridge member 72 carried by the leg members 52 and 54 to span the opening 62. A closure member 92 is disposed on the upperside 44 of the base plate 40 adjacent the opening 62. A spring member 80 is connected between the frame member 79 and the closure member 92 normally to urge the closure member 92 to close the opening 62 whenever the flow in the passageway 12 or 14 is less than 5 psi.
