120075 2" Range Guard Mechanical Gas Shut off Valve

The Range Guard 2" Mechanical Gas Shut Off Valve (Part No. 120075) is the flagship high-capacity safety anchor for industrial gas mains and large-scale utility manifolds. Engineered for environments where a 2-inch supply is mandatory, such as industrial baking ovens and massive food processing lines, this valve provides the highest flow coefficient (Cv) in the Range Guard lineup. It ensures that even during peak production hours, your high-BTU equipment receives a steady fuel supply without the pressure fluctuations that cause appliance starvation.

Operating on a principle of passive reliability, the 120075 is a purely mechanical fail-safe. It is held open by a high-tension control cable connected to the system's Universal Control Head (UCH). In the event of a fire, the release of cable tension allows a heavy-duty internal spring to slam the gate shut, providing an immediate barrier in the fire hazard zone. This 2-inch model is precision-machined from industrial-grade cast bronze, specifically designed to withstand the thermal stress and mechanical vibrations of industrial life-safety engineering applications.

The 120075 must be installed by a licensed fire suppression technician in accordance with the Range Guard system design manual and applicable local gas codes. The valve interfaces directly with the UCH via a mechanical cable release, and cable tension must be set to factory specifications to ensure the spring holds the valve fully open during normal operation.

Due to its robust industrial casting, the 120075 is significantly heavier than smaller valves. It is recommended that the 2-inch NPT piping be securely supported with heavy-duty hangers on both sides of the valve to prevent stress on the manifold during the high-torque mechanical trip sequence. After installation, the technician must verify full valve travel by performing a manual trip test and confirming positive gas shutoff before the system is placed back into service.

Is the 2" valve suitable for a facility-wide gas main?

Yes. The 120075 is frequently used to protect the 2-inch gas main that feeds multiple cooking batteries in a large institutional mega-kitchen. By installing the shut-off at the main or sub-main level, you ensure that the entire facility's fuel source is isolated during a discharge event.

Can this 2" valve be used in non-kitchen industrial hazards?

Absolutely. Under the Industry Guard banner, the 120075 is the specified choice for industrial quenching tanks and dip tanks. Its 2-inch bore is designed to handle the high-volume flammable gas requirements of heavy manufacturing without creating a restrictive bottleneck in the piping.

Does the 2" valve require specialized mounting?

Due to its robust industrial casting, the 120075 is significantly heavier than smaller valves. It is recommended that the 2-inch NPT piping be securely supported with heavy-duty hangers on both sides of the valve to prevent stress on the manifold during the high-torque mechanical trip sequence.
