Robertshaw 850-001 1/2" Direct Spark Gas Valve 24V

The Robertshaw 850-001 1/2" Direct Spark Gas Valve is a fuel control component that regulates the flow of natural or LP gas to the burner during a heating cycle. By 24-volt electrical signal opens and closes the internal valve in response to ignition commands, allowing gas to reach the burner only when required for combustion within HVAC systems. It is connected within the gas supply line ahead of the burner assembly to coordinate fuel supply with the ignition sequence. Controlled gas flow supports stable burner ignition, maintains consistent combustion and contributes to safe, uninterrupted equipment operation.
