Robertshaw 1751-012 Knob

The Robertshaw 1751-012 Dial Knob is a mission-critical replacement component engineered for the Unitrol 7000 series and Robertshaw 700 series combination gas valves. This beige gas valve knob features the standard "Off-Pilot-On" positions, providing precise manual control over gas flow for commercial cooking equipment and residential heating systems. Designed as a rugged HVAC replacement dial, it ensures a secure fit on the valve's stem to prevent slippage during cycles. As a veteran-grade gas valve control part, this knob is frequently utilized in standing pilot assemblies where tactile feedback and high-temperature durability are non-negotiable. Whether you are performing a routine service or a complete valve overhaul, matching the exact Robertshaw part number is essential to maintain proper alignment with the internal cam. This component is cross-compatible with several high-output heating valve models, ensuring reliable performance in the field without the risk of common mechanical failure associated with generic alternatives.

Is the 1751-012 knob compatible with all 700 series valves?
This knob is designed for the standard Robertshaw 700 series and Unitrol 7000 valves but is not intended for use with specific 700 series pilot ignition valves that require different stem configurations.

What is the stem size for this replacement dial?
The 1751-012 fits a 1/2-inch diameter D-shaped stem, which is the industry standard for most 7000-type gas cock dials.

Can I use this knob on a millivolt gas valve?
Yes, provided the valve is part of the 7000 or 700 series families, it will facilitate the manual "press-to-light" pilot function correctly.
