Honeywell VS820A1070 PowerPile Millivolt Combination Gas Valve

The Honeywell VS820A1070 is a millivolt combination gas valve designed for natural gas heating applications. This control features PowerPile operator technology, which eliminates the need for external power sources by generating its own millivoltage through the pilot flame.

Key Features:

• PowerPile millivolt operator for self-powered operation
• 3/4-inch NPT inlet and outlet connections
• Integrated safety shutoff valve for pilot flame failure protection
• Standard pressure regulator (V5306A type) included
• Manual gas control knob with Off, Pilot, and On positions
• Ambient temperature range: 32°F to 175°F (0°C to 79°C)
• Natural gas application with 6.0 inch W.C. regulation
• Quick-connect terminals for easy wiring
• Pilot flow adjustment screw for flame optimization

This combination gas control integrates multiple functions into a single unit, including manual shutoff, automatic safety control, pressure regulation, and valve operation. The PowerPile operator generates electricity from the pilot flame heat, providing reliable millivolt power to open and close the main gas valve based on thermostat demand. Safety shutoff occurs automatically within 2-1/2 minutes if pilot flame is extinguished, blocking gas flow to both pilot and main burner.

Commonly used in furnaces, radiant heaters, and other gas-fired heating equipment including Detroit Radiant Re-Verber-Ray systems. The valve includes reducer bushings for flexible installation options and features both straight-through and side outlet configurations for versatile piping arrangements.
