A modular container filling apparatus includes a simple pilot valve which can be operated by a push button, a bottle-engaging yoke, or a manual valve at the distal end of a bucket filling hose. The modular construction of the apparatus allows a plurality of units to be mounted side by side on a modular water manifold by bayonet-type sealing connections. An anti-foam venturi and spout mixes chemicals with the water and minimizes foaming when filling a bottle. A plurality of chemicals can be selected by a rotational selector without intermixing.

1. A container filling device, comprising:a) a supply of liquid under above-atmospheric pressure; b) a liquid outlet at atmospheric pressure; c) a backflow preventer interposed between said liquid supply and said liquid outlet; and d) a valve interposed between said liquid supply and said backflow preventer, said valve including: i) a discharge conduit upstream of said backflow preventer communicating with said backflow preventer; ii) an intake conduit communicating with said liquid supply; said discharge conduit and said intake conduit forming a valve seat therebetween; iii) a resilient valve element selectively engageable with said valve seat to close said valve, said valve element having a first portion communicating with said intake conduit, and a second portion communicating with said discharge conduit; iv) a chamber separated from said intake conduit and said discharge conduit by said valve element; v) said first portion of said valve element having a relatively small aperture therein interconnecting said intake conduit and said chamber; vi) said second portion of said valve element having a relatively large aperture therein interconnecting said discharge conduit and said chamber; vii) a plug member arranged and biased to close off said relatively large aperture; and viii) an actuator arranged to selectively move said plug member against said bias to open said relatively large aperture and thereby cause the liquid pressure in said intake conduit to raise said resilient valve element off said valve seat.
