		Fully integrated sensors to detect all critical positions	- No external wires exposed to wash-down and mishandling - Extra security to monitor seat positions during cleaning
		No compressed air required for servicing	Easy and efficient maintenance
	7	Balanced upper and lower shafts (as standard)	- No hydraulic blocking - Resistant against pressure spikes - Flexibility in either flow direction through the valve (top-to-bottom or bottom-to-top) without water hammering
	7	Reduced cleaning fluid losses to drain	- Chemical and water savings - Cleaner environment due to fewer chemicals and fluids spilling to the floor
	8	Large separation cavity drain port	Less product risk and prevention of pressure build-up that could cause cross-contamination
	9	Flush cavity spray fixed connection (as standard)	- Enhanced cleaning - Removal of residual media in separation cavity when full CIP is not readily available - Hard-piped flush can be used without need to be removed during valve maintenance
	9	Light overall weight	Easier handling for maintenance

Theory of Operation

Double seat mix proof valves are used to efficiently process two different fluids (typically product and CIP) through the valve simultaneously. The mix proof design has two seats which isolate the upper and lower pipe lines when the valve is in the fail-safe closed position. The atmospheric vent cavity in between the seats creates a path for any leakage should the seals fail as well as a drain for CIP solution during seat cleaning. An external CIP spray flush is included to provide enhanced cleaning of the leakage and vent cavity while the valve is closed or open during production.

Valve Closed	Optional Lower Seat Clean
Valve Open	Optional Upper Seat Clean
