Hayward H-Series Heater Natural Gas Valve (150-400 MV) | HAXGSV0001

Restore the safe and consistent firing of your pool heater with the Hayward HAXGSV0001 Natural Gas Valve. This genuine OEM component is a critical part of the combustion system for Hayward H-Series Millivolt (MV) heaters. It acts as the primary gatekeeper for fuel, opening to allow gas to the burner tray only when the pilot light is established and all safety limit switches are closed.

Gas valves can fail due to internal diaphragm wear, corrosion from moisture, or debris in the gas line. A faulty valve may result in a pilot that won't stay lit, a heater that refuses to engage the main burners, or intermittent heating cycles. Replacing a malfunctioning unit with this factory-authorized valve ensures your heater operates with the precision and safety intended by the manufacturer.

Features

Millivolt System Compatibility: Specifically engineered for "standing pilot" heaters that operate on millivolt technology. This valve is powered by the small electrical current generated by a thermopile, meaning it functions without the need for an external 120V or 240V power source.

Precision Gas Flow Regulation: The HAXGSV0001 is calibrated to maintain the correct manifold pressure for Hayward’s 150,000 to 400,000 BTU atmospheric heaters. Proper regulation ensures a clean, blue flame and prevents "sooting" or inefficient combustion.

Integrated Pilot Safety Circuit: Features a built-in safety shut-off mechanism. If the pilot light goes out, the valve automatically detects the drop in millivolts and snaps shut, preventing unburned natural gas from accumulating inside the heater cabinet.

Durable, Weather-Resistant Housing: Constructed from heavy-duty materials designed to withstand the temperature fluctuations and humidity common in outdoor pool equipment pads. The internal components are treated to resist the corrosive effects of the environment, ensuring long-term reliability.

Genuine Hayward OEM Replacement: As a factory-original part, this valve features the exact port sizing and mounting configuration required for a direct fit. Using the genuine HAXGSV0001 guarantees that the internal spring tensions and safety thresholds match your H-Series heater's original engineering.
