Propane LPG Gas Fire Pit Control Safety Valve with Thermocouple and Knob A compact, reliable control valve assembly designed to manage fuel flow and monitor flame presence in propane and LPG fire pits and gas heaters. This unit combines a manual control knob with a flame failure device and thermocouple to help stop gas flow when the pilot or main flame is not detected. Key benefits Direct flame monitoring: Builtin thermocouple senses flame presence and works with the flame failure device to stop gas flow if the flame goes out. Simple manual control: Intuitive knob provides pilot, on, and off positions for straightforward operation and adjustment. Wide compatibility: Intended for use with propane and LPG systems in fire pits, patio heaters, grills, and other gas appliances that accept a thermocoupleoperated safety valve. Durable construction: Metal valve body and components are designed for repeated operation and long service life in outdoor and indoor gas appliances. Easy replacement and maintenance: Compact design makes it suitable as a direct replacement for existing thermocouple valve assemblies in many appliances. Function and performance Flame failure device: Automatically interrupts gas supply when the thermocouple no longer detects heat from a flame, reducing unintended gas flow. Thermocouple integration: Provides continuous voltage feedback to the valve based on flame temperature for responsive shutoff. Manual knob control: Allows user selection of pilot lighting and normal operation modes, plus a secure off position. Compatibility and installation For propane and LPG appliances that use thermocoupleoperated safety valves, including fire pits and gas heaters. Compact form factor fits many common valve mounting arrangements; verify fit against your existing valve before . Installation requires basic gas fitting knowledge. For safe and correct setup, professional installation or verification by a qualified technician is recommended. Typical use scenarios or the safety valve on a backyard propane fire pit to restore flame control and pilot operation. Retrofit a patio gas heater that uses a thermocouple valve to improve flame monitoring and enable manual pilot control. Maintain or service outdoor cooking appliances and grills that require a combined control valve and flame failure device. What to check before buying Confirm your appliance uses a thermocoupleoperated safety valve and that the physical mounting and inlet/outlet connections match this valve. Ensure the valve orientation and knob function match your existing control assembly for straightforward replacement. This control valve assembly provides a practical combination of manual control and flamesensing shutoff for propane and LPG fire appliances where thermocoupleoperated valves are required.
