Product Highlights
Description
The Taco Geo-Sentry® Zone Valve enhances the overall performance of any geothermal system. The unique patented technology in the Geo-Sentry® utilizes a microcircuit based logic to control a gear driven electronic actuator which drives a ball valve based body design. All this adds up to a geothermal zone valve that leads the industry in energy efficiency, flow capacity (Cv), shutoff pressure rating, ease of installation, diagnostic capability and the number of valves (12) that can be use on a standard 40VA transformer. The Taco Geo-Sentry® zone valves are available in sweat, threaded and 3-way configurations.
Features
- Up to 93% less energy usage

Product Q&A
2 QuestionsQ: What does (normally open), (normally closed) mean? Does it matter whether they are normally opened or closed as they will be opening and closing numerous times, depending on the demand. Thanks

Verified Reply- Supplyhouse.com TeamNormally closed valves are designed to block flow through the valve and are commonly used for emergency safety. During usual operation, these devices use a spring to remain closed. The valve will open when the system begins to experience over pressure to ensure safety. Once pressure begins to normalize, it will automatically close. Normally open valves are also used as safety devices. However, unlike normally closed valves, these parts work to maintain low pressure in a system. Normally open valves are designed to allow liquid or gas to flow through in usual circumstances. As the system builds pressure, they will begin to shut in order reduce and regulate pressure levels. In some extreme over pressure situations, they will close almost entirely.
Q: what does CV on a zone valve mean?

Verified Reply- PexSupply StaffCv is an expression of the pressure drop through a piping component. It quantifies how much flow is necessary to create a 1 psi pressure drop (2.31 feet of head) across a piping component.
