Robertshaw 110-280 Valve

The Robertshaw 110-280 is a high-performance unitrol gas valve engineered specifically for liquid propane (LP) water heating systems in commercial and high-demand applications. This LP water heater gas valve features a 1/2” pipe inlet and a 1/2” inverted flare outlet, providing a secure, leak-resistant connection for standard hot water heater gas control setups. Rated for a maximum temperature of 180°F, it is an essential component for technicians servicing commercial-grade tanks that require higher thermal thresholds than standard residential models. The integrated 5-1/2” sensing element ensures precise temperature regulation, while the built-in, non-cycling Energy Cut-Off (ECO) system acts as a critical safety barrier, shutting off the gas supply if water temperatures exceed safe limits. This Robertshaw 110 series universal replacement kit is designed for straightforward field installation, making it the preferred choice for contractors seeking a reliable hot water gas valve replacement for various liquid propane tank configurations.

• Commercial Grade Calibration: Pre-set for a 180°F high-stop, ideal for commercial water heating requirements.
• Universal Compatibility: Part of the Robertshaw Uni-Kit series, designed to replace numerous OEM liquid propane gas valves.
• Enhanced Safety: Features a non-cycling ECO system that provides a secondary layer of protection against overheating.
• Reliable Sensing: Includes a 5-1/2” copper sensing tube for accurate and responsive thermal feedback.
• Simplified Installation: Standard 1/2” connections allow for direct integration into existing gas plumbing without extensive modifications.

What are the specific port sizes for the Robertshaw 110-280?
This valve is equipped with a 1/2" NPT pipe inlet and a 1/2" inverted flare outlet, which is a standard configuration for many LP water heater gas valves.

Can the ECO system be reset if it trips?
The ECO system in the 110 series is non-cycling. If it detects an over-temperature condition and opens, the control will no longer function, and the entire gas control valve must be replaced to ensure system safety.

Is this valve compatible with natural gas systems?
No, the 110-280 is calibrated specifically for liquid propane. Using this valve with natural gas is unsafe and can lead to improper combustion and equipment failure.
