Abstract
A regulated control valve assembly is provided for use in a water purification system having a reverse osmosis unit to produce relatively purified water from a feed water supply of ordinary tap water or the like. Purified water produced by the reverse osmosis unit is supplied to a purified water chamber in a storage vessel ready for dispensing on demand by operation of a faucet valve. The control valve assembly includes a throttle valve responsive to the purified water chamber reaching a substantially filled condition to throttle or halt feed water inflow to the system. In addition, the control valve incorporates a pressure regulator for shifting the throttle valve in a manner regulating the pressure of feed water supplied to the purification system to a predetermined, relatively low pressure level.
