| 20120097618 | AERATION CONTROL VALVE SYSTEM FOR WATER TREATMENT SYSTEM AND METHODS FOR USING SAME - An aeration control valve system may be used with a water treatment system to control aeration and flow of water in accordance with various operating cycles. The aeration control valve system pumps air into the water treatment system to provide an air charge for aerating the water to facilitate water treatment. The aeration control valve system may pump air into the water treatment system at atmospheric pressure or may pump air at higher pressures such that the air may be recharged while also treating the water. The aeration control valve may also control the release of air from the water treatment system. The operating cycles may include, for example, a service cycle, a backwash cycle, an air regeneration cycle, a service/air charge cycle, an air release cycle, and a rinse cycle. | 04-26-2012 |
| 20110042282 | PRESSURE-CONTROLLED LIQUID SUPPLY SYSTEM AND PUMP CONTROL DEVICE FOR USE THEREIN - A pressure-controlled liquid supply system uses a pump control device to switch a pump on and off in response to a pressure level in the pumped liquid. The pump control device minimizes short cycling of the pump by preventing shut off of the pump while a flow is present through the pump control device and by delaying the shut off of the pump. The pump control device also avoids a significant drop in the output pressure by creating a reduced pressure zone, which provides the switch pressure used to switch the pump off. | 02-24-2011 |
| 20090230341 | PIVOTABLE CONTROL VALVE ASSEMBLY FOR WATER TREATMENT DEVICE - A pivotable control valve assembly may be used with a water treatment device in a water treatment system. A pivotable control valve assembly may be pivotable relative to the water treatment device to allow user controls on the pivotable control valve assembly to be oriented in a desired user access position. In a water treatment system including a plurality of water treatment devices, for example, one or more pivotable control valve assemblies may be pivoted such that user controls for each of the water treatment devices are in desired user access positions. | 09-17-2009 |
