Typical Components

MOTORIZED ALTERNATING VALVE FEATURES (MAV)
	Engineered for duplex alternating system 1-1/4” to 2” Motorized Alternating Valves Full porting with minimal pressure loss Provides for no raw water bypass during regeneration Low voltage drive assy controlled by valve circuit board Operating pressures 20psi-125psi Operating temperatures 40˚ F - 110˚ F Patent seal spacer stack assy Hydraulically balanced piston valve Proven and reliable Excalibur DC drive assy
NO HARD WATER BYPASS (NHWB)
	Engineered for duplex alternating with progressive flow & system controller applications 1” to 3” No Hard Water Bypass Valves 316 stainless & composite materials of construction Designed for use in multiple tank configurations Proven and reliable Excalibur DC drive assy Hydraulically balanced piston valve Patent seal spacer stack assy Operating pressures 20psi-125psi Operating temperatures 40˚ F - 110˚ F Low voltage drive assy controlled by valve circuit board Full porting with minimal pressure loss
EXCALIBUR CONTROL SYSTEM
	Excalibur System Controller may operate 2-6 vessels 1” to 2” Control Valve Engineered Systems System diagnostic & programming information download Two fused single pole double throw (SPDT) relay outputs Front panel displays for time of day, day of week, days until next regeneration, current system flow rate & total system volume utilized System regeneration types progressive flow, alternator, series, and random options Solid state processor friendly front panel programming Front panel LED status indicators for online, standby, and regeneration Single demand based output meter Coin cell lithium battery for backup time of day
MINERAL TANKS
	Excalibur mineral tanks are made of high pressure composite materials - LLDPE liner with FRP filament winding outer shell Flanged tanks manufactured with continuous seamless inner liner shell with a solid anodize aluminum cast flange This design provides excellent strength, durability and leak free service Maximum operating pressure 150psi Maximum operating temperature 120˚ F Mineral tanks are PED certified
ASSEMBLED BRINE TANKS
	Excalibur brine tanks are rotationally molded of a high density polythylene for exceptional stress-crack resistant properties increased durability Injection molded plastic HDPE grids available for dry salt storage applications Brine float to eliminate brine tank overflowing Safety float brine valve delivers water demand for high flow brining application and refill Float eliminates pre-checking during brine refill when air is in the brine line could cause excessive flow rates Brine float is enclosed inside a brine well with cap and secured with a two piece overflow set Air check valve to initiate slow rinse cycle after brining complete
RESIN
	Excalibur C-800 water softening resin has a minimum 8% cross link gel type sodium form high capacity polystyrene ion exchange resin Performance maximum capacity of 30,000 grains per cubic foot when regenerated with 15lbs of salt Resin is solid containing no plates shells agglomerates or other shapes for high efficiency maximum capacity performance Excalibur premium water softening resins are manufactured in Canada
GRAVEL SUPPORT BED
	Excalibur uncrushed gravel has a highly spherical shape that promotes good flow and even distribution support bed Gravel will maintain the quality of the softened water Multi depth layered gravel support bed for maximum flow rates with minimum pressure drop
WATER DISTRIBUTION
	Excalibur high impact FDA approved hub and lateral high flow distributors are utilized to evenly collect and distribute the flow of water over the entire resin bed.
PROGRESSIVE FLOW
	Progressive flow provides minimum to maximum peak flow rates utilizing one or all of the vessels in the design configuration to satisfy current demand. This system will utilize and operate outlet isolation valves with a predetermined flow rate set point to bring online additional units to meet peak flow rate requirements. This system configuration determines the need to regenerate based
