Resideo VF06-100-SUSUT Valve

The Resideo VF06-100-SUSUT is a high-performance 1/2 inch boiler fill valve designed for the automatic regulation of feed water in closed hydronic heating systems. Engineered for expansion tank mounting, this dual-unit pressure reducing valve features an integrated check valve and manual shutoff, streamlining your installation by reducing the number of individual components. As the professional choice for field replacements, the VF06-100-SUSUT is the direct cross-reference for the Watts 911-M3, 0386460, and 911 series, ensuring seamless compatibility during retrofits.

Built with a durable brass body, this dial-set boiler feed valve utilizes a balanced-seat design, ensuring that inlet pressure fluctuations do not affect the discharge pressure. The fast-fill feature allows for rapid system charging, while the accessible dial enables precise pressure adjustments from 8 to 50 psi without the need for external gauges. Each unit includes a 1/2" union nut with both male NPT and female sweat tailpieces, providing maximum flexibility for hydronic system pressure control in any mechanical room configuration.

• Streamlined Installation: Combined pressure reducing valve and check valve design minimizes leak points and labor time.
• Versatile Plumbing: Includes union connections for 1/2" NPT and sweat fittings, fitting standard boiler feed water lines.
• Pressure Stability: Balanced-seat technology maintains a consistent 15 psi factory setting despite city water pressure spikes.
• Service Friendly: Features an integrated 1/4" NPT gauge port and manual shutoff for easy system diagnostics and maintenance.
• Direct Replacement: Verified drop-in for Watts 911-M3 and legacy 911-model valves.

Is the check valve integrated?
Yes, the Resideo VF06-100-SUSUT includes a built-in check valve to prevent backflow into the potable water supply, meeting standard hydronic safety requirements.

What is the maximum pressure and temperature rating?
This valve is rated for a maximum operating pressure of 150 psi and can handle medium temperatures up to 140°F (ambient up to 212°F), making it suitable for high-demand residential and light commercial boilers.

Can I install this on a system that already has a backflow preventer?
Technicians often use this as a direct replacement in systems where a standalone backflow preventer is already present. Its compact footprint is ideal for tight mechanical spaces.
