The XHQPTG and XHQFZ flameout devices are normally closed 12V DC solenoid valves designed as off valves and stop valves for diesel engines and generator systems. Built to stop fuel flow quickly, they serve as a safety component in flameout and emergency shutdown applications. The normally closed (NC) configuration ensures fuel is held off by default and only energizes to open when required by the control system. Key benefits Enhanced safety: quick and reliable shutoff of fuel to extinguish flame events or enable emergency shutdown. Failsafe operation: the NC configuration keeps the valve closed until an appropriate control signal energizes it, reducing the risk of unintended fuel release. Easy integration: compact solenoid design suitable for common diesel engine and generator control circuits and flameout systems. Targeted fire and engine protection: specifically designed for use as a flameout device and off valve in diesel engine applications and generator parts. Key attributes Models: XHQPTG, XHQFZ Function: Off valve stop solenoid valve for diesel engine fuel shutoff and flameout control Configuration: Normally Closed (NC) Voltage: 12V DC Applications: Diesel engines and generator systems requiring a flameout/stop valve component Compatibility: Suitable for incorporation into flameout devices and related safety/shutdown circuits Size/Voltage indication: 12V DC operation Use cases Emergency shutdown of a standby diesel generator: when a flameout or fault is detected, energize the valve to open or close as required by the control logic to halt fuel supply and stop combustion. Flameout safety integration on a diesel engine: install as part of a safety system that automatically shuts off fuel flow in response to flame detection signals, reducing risk of engine damage or fire. Maintenance replacement in diesel equipment: worn or failed off valves in generator or engine setups that require a NC 12V DC solenoid valve for reliable shutdown capability. These valves are positioned as reliable components for diesel engine flameout and generator safety systems, offering a straightforward, controlled means to stop fuel flow and support safe operation.
