Taco, Inc.: ZONE VALVE
May 17, 2001
The ESP (energy storage principle) zone valve is a gear-driven, capacitor-powered valve, which replaces the traditional spring with a Prostar Gold Cap capacitor for returning the valve to its normal position. Also, the old style synchronous ac motor has been replaced with a high-torque, high-efficiency miniature motor. These two innovations replace two traditional failure items, the motor and spring, to deliver greater reliability and performance, says the company. Plug-in connectors make wiring quick and easy, the manufacturer says.
