iThermostatic Valves: Used in a tub/shower to set a specific water temperature to within plus or minus one degree. When temperature fluctuations occur at the water inlets, a thermal actuator adjusts the hot and cold rate to maintain the original temperature setting. Acts as a scald guard.
Diverter Valves: Used to divert water between two faucets (for example, a shower head and tub spout). Also referred to as Transfer Valves.
Pressure Balance Valves:reacts to changes in pressure of water being delivered such that the volume of water that leaves the pressure balance valve is a constant mix of hot and cold even if the pressure of one or both of the sources changes. Acts as a scald guard.
Volume Control Valves:Used to regulate the flow of water through the faucet. May also be known as flow control valves, flow divider valves and/or bypass flow regulators.
For the purpose of turning the water supply off and ensuring that no water will run through the valve of a fixture that needs repair. This allows the user to keep other plumbing fixtures active while the damaged fixture is replaced.
