3/4″ 2-Way Zone Sentry Press-Zone Valve, Normally Closed

Taco Z075P2-2 Zone Sentry® Valve – 3/4″ Press, 2-Way Normally Closed, 24V Control

The Taco Z075P2-2 is a 3/4″ press connection, 2-way normally closed zone valve designed for closed-loop hydronic heating and chilled water systems. This 24V low-voltage valve offers precise on/off control and integrates easily into multi-zone distribution piping for residential and light commercial applications.

Part of the Zone Sentry® series, the Z075P2-2 is engineered for high-efficiency system performance, providing reliable actuation while consuming significantly less energy than traditional zone valves. The valve is rated for use in a wide range of hydronic configurations, including baseboard, panel radiators, fan coils, air handlers, radiant manifolds, and compatible chilled water applications.

Installation Considerations

This valve is designed for closed hydronic systems only and is not intended for potable water. Proper installation requires press tools compatible with standard copper press fittings. For optimal performance, the valve should be wired according to the system control schematic using Class 2 24V power. Installation should be performed by licensed HVAC or plumbing professionals in accordance with local codes.

Professional Use and System Integration

The Taco Z075P2-2 is a reliable choice for zoning in multi-load hydronic systems. It supports integration with zone control panels, thermostats, and pump relays. Its low watt draw is suitable for applications requiring energy-conscious design, such as radiant systems and high-efficiency boilers. Field serviceability is enhanced by the actuator’s removable design without requiring system drainage.
