1 Hydroni essories ESP Zone Valve he ao ESP is the most intelligent zone valve in the world. he unique patented tehnology in the ESP utilizes a miroiruit based logi to ontrol a gear driven, apaitor powered atuator whih drives a ball valve based body design. ll this adds up to a zone valve that leads the industry in flow rate apaity, shutoff pressure rating, ease of installation, energy effiieny, diagnosti apability, and the number of valves () that an be used per standard 0 V transformer.

2 he ao ESP Zone Valve. M Driven by reliability. he ESP thinks for itself. he heart of the ESP Zone Valve is the Energy Storage Priniple. he ESP is a gear driven, apaitor powered valve. Its unique, patented tehnology replaes the typial spring with a Prostar apaitor for returning the valve to its normal position. Moreover, the old style synhronous motor has been replaed with an exeptionally reliable high torque, high effiieny miniature motor. hese ao innovations replae two failure items, the synhronous motor and the spring, to deliver dependability you never thought possible. Inside the fashionably blak box is a miroproessor that monitors the valve s operations. When a thermostat alls, the proessor makes sure the apaitor is fully harged, then sends power to the motor. he motor turns a set of gears that rotates the ball valve 90 to the Open position. One at the Open position, the motor turns off. he remains lit as long as the thermostat is alling. One the zone has been satisfied, the apaitor disharges a portion of its stored energy and the motor turns the ball valve another 90 to the losed position. n on-board optial sensor ontinuously ensures the proper Full Open and Full losed position of the ball. Universal thermostat ompatibility. No matter the brand or style of thermostat hanging on the wall, the ESP works with them all. Now you an get all the features you want in a zone valve and a thermostat without having to worry about ompatibility issues. Manual operation is a breeze. No need to worry about stripping gears or damaging the spring with the ESP. With the push of a button, the gears disengage and the valve an be rotated in any diretion, to any position. Just release the button and the gears re-engage. What s more, the valve automatially resets itself to the proper Manual Operation Button with utomati Reset Indiator Light Plug-In erminals tuator Head an Be Mounted In Either Diretion Easy, One-Handed Removal Blowout-proof Stem Ball Valve Design, High v 5 PSI Shutoff Pressure Sweat or hreaded /, /, and Bi-Diretional Flow -Way Valve Option

3 Smart for a lot of reasons. ball position one power is restored. So you an t leave the valve open by mistake. Easy, easy, and easy. Plug-in srew terminals make the ESP a breeze to install and operate. he valve an be installed in any diretion, in any orientation, and features a dependable / turn one-handed twist lok for easy operator removal. he atuator head is a snap to replae, and an be mounted to the valve body in either diretion, great for tight baseboard jobs. Let there be light. he external shows you the full funtionality of the valve s operation and thermostat status, making it a perfet ompanion to ao s line of eletroni zone valve ontrols. Less is more. With the ESP, there are fewer parts to wear out, so the life of the valve is greatly inreased. Miroiruit tehnology lowers the amp draw so you an install up to valves per 0 V transformer, or use a smaller transformer. Either way, you save on transformer osts. nd beause there s no bulky synhronous motor, the ESP has a lower profile to fit into tighter spaes. Last, the ESP features a universal atuator, so it fits all sizes of valves and redues inventory. version for all of your needs. he high flow, low head loss harateristis of the ESP ombined with its ompat design and 5psi shutoff pressure rating makes the ESP the most flexible valve on the market today. No matter your appliation, there is an ESP Zone Valve to suit your needs.
