The Taco Z075C2-1 SWT 3/4inch Sentry Zone Valve Sweat 2-Way is a reliable and efficient option for controlling water flow in hydronic heating and cooling systems. Here’s a breakdown of its key features and functions:


  • On/Off Control: Provides 2-way control, allowing water flow to either bypass the zone (valve closed) or through the zone (valve open).
  • Automatic or Manual Operation: Compatible with both automatic control signals (e.g., thermostats) and manual override buttons for flexible operation.
  • Energy Efficiency: Up to 93% less energy consumption compared to traditional zone valves, thanks to its unique electronic actuator technology.
  • High Flow Capacity: Offers excellent flow rates for efficient system operation, even with 3/4-inch piping.
  • Durable Construction: Built with brass and stainless steel components for long-lasting performance and corrosion resistance.

Key Features:

  • Universal Installation Orientation: Can be installed horizontally or vertically for flexibility in piping layouts.
  • Quick Connect Wiring: Simplifies electrical connections for quicker installation.
  • Multiple Valve Options: Available in different sizes and connection types (sweat, flange, soldered) to match various system requirements.
  • Diagnostic Capability: Features LED indicators and error codes for easy troubleshooting.
  • Normally Closed: This specific model (Z075C2-1) is normally closed, meaning the valve shuts off water flow in the absence of a control signal, ideal for most heating system applications.


  • Hydronic Heating Systems: Ideal for controlling hot water flow to individual zones in radiant heating, baseboard heating, and fan coil systems.
  • Chilled Water Systems: Suitable for managing chilled water flow in zoned air conditioning systems.
  • Domestic Hot Water Recirculation: Can be used to control water circulation in hot water recirculation systems for instant hot water at taps.

Things to Consider:

  • System Compatibility: Ensure the valve size and connection type match your existing piping specifications.
  • Control Signal Compatibility: Confirm the valve control voltage and type (dry contact, voltage signal) align with your control system.
  • Normally Closed vs. Normally Open: Choose the appropriate configuration (normally closed or open) based on your system requirements.
  • Professional Installation Recommended: While technically feasible for DIYers with plumbing experience, proper installation, especially involving electrical connections, is best handled by a qualified plumber.

Overall, the Taco Z075C2-1 SWT is a versatile and efficient zone valve offering reliable control, energy savings, and convenient features for various hydronic heating and cooling systems.
