XHQ-PT-NO Normally Open Fuel Shutoff Solenoid DC12V DC24V Diesel Generator Flameout Device Electric Stop Solenoid

Model Classification

• XHQ-PT-NO 12V: For 12V battery diesel gensets, small car diesel engines, portable rental power units
• XHQ-PT-NO 24V: For 24V heavy-duty diesel generator, truck, engineering machinery, large stationary power sets
• Contrast type: XHQ-PT-NC (Normally Closed, power-off pull flameout, different control logic, cannot interchange with NO)
•  

Wide Application Range

1. Small silent / open frame diesel generator sets (10kW~200kW) with 12V/24V battery system
2. Weichai, Yuchai, Yunnei, Perkins, Deutz single-cylinder & multi-cylinder diesel water pump units
3. Construction machinery diesel engines, agricultural diesel machinery, small marine auxiliary diesel engines
4. Original flameout solenoid burnout, unable auto stop, no reset after shutdown replacement spare parts
5. Generator OEM complete set matching, power rental & maintenance shop universal shutdown spare parts stocking

Common Failures Solved

• · Old NC power-off pull solenoid incompatible with new controller, cannot auto stop on fault alarm
• · Wrong voltage solenoid leads to insufficient pull force, unable to cut fuel completely, engine fails to shut down
• · Thin coil cheap solenoid overheat and burn after long energization, frequent shutdown failure
• · Solenoid without automatic reset, need manual pull back wire rope every time before startup
• · Original flameout device broken, unable to realize automatic protection shutdown function of genset controller
