NPT x 3/4 in. NPT PowerPile Millivolt Combination Gas Valve with 3.5 in. The generator, heated by the pilot burner flame, provides the electrical energy to operate the combination gas control. A millivoltage thermostat with suitable accessory controls completes the automatic control system for the heating appliance.

What is a typical control voltage on a furnace gas valve?

Most residential heating and cooling systems have 24 volt control systems.

How does thermocouple controlled gas valve?

The thermocouple in a gas furnace is designed to keep the gas valve open through its electric voltage. If the pilot light goes out, the loss in heat causes the voltage between the two pieces of metal to drop, and this shuts the valve and reduces the combustion risk.

How does a gas valve work?

The furnace gas valve operates by electromagnets. The primary valve — also known as the safety valve — supplies gas to the pilot light. The second valve — also known as the main valve — allows gas to flow to the burner trays. The thermocouple (or thermopile) generates the power holds the safety valve open.

How many millivolts does it take to open a gas valve?

on/off switch. Thermopile Output- MAIN BURNER ON: 110 mv minimum required for system to operate consistently. If lower than 110 mv, conduct valve operating head test.

What does sit gas valve mean?

Sit valve is used on most fireplaces produced after 1999. Uses Thermopile and Thermocouple (quick drop out) The automatic shut-off valve provides particularly silent operation and is supplied by thermopile, without requiring external electrical energy. Pilot outlet flow is adjustable.
