	Fontaine's SERIES 20 Sluice Gate is a highly versatile flow control gate with various types of mountings.
	The Fontaine SERIES 25 gate is designed to control water flows in channels.
	The Fontaine SERIES 40 weir gate is used to control flows in different applications by opening downwards and allowing water flow over the stainless steel plate.
	The Fontaine SERIES 60 is the simplest way to prevent flows of water from returning back into pipes or openings. The gate design is such that whatever the size, a small flow will open the gate in negative pressure and will remain watertight for positive pressure.
	The Fontaine SERIES 70 is the simplest way to prevent water flows from returning in to pipes or openings. The gate design is such that whatever the size, a small flow will open the gate in negative pressure and will remain watertight for positive pressure.
	The Fontaine SERIES 95 Stop Logs are an easy and economical way to control flow in a channel. Their lightweight construction makes them easy to handle and the UHMWPE (ultra high molecular weight polyethylene) guide eliminates all metal-to-metal contact between the slide and frame, thereby allowing the logs to slide up and down with minimal friction.
