TQJ-4 LNG Pressure Regulator – Precision Control for Natural Gas Trucks
The TQJ-4 LNG Pressure Regulator is a high-performance pressure-reducing valve specifically engineered for liquefied natural gas (LNG) applications in heavy-duty trucks. Designed with industrial-grade materials and cutting-edge flow control technology, this regulator ensures stable outlet pressure, safe operation, and maximum fuel efficiency under demanding road and temperature conditions.
Reliable Pressure Reduction for LNG Fuel Systems
This LNG pressure reducer is ideal for natural gas-powered commercial vehicles, including long-haul trucks, buses, and fleet vehicles. The TQJ-4 precisely manages high-pressure LNG stored in cryogenic tanks and reduces it to a safe and consistent working pressure required by the engine. This function is critical to avoid pressure fluctuations, ensure engine stability, and extend system lifespan.
Durable Construction & LNG Compatibility
Manufactured using low-temperature-resistant materials, the TQJ-4 pressure regulator offers outstanding resistance to cryogenic environments. It is specifically built to handle LNG’s extremely low temperatures and high volatility, ensuring no leakage, corrosion, or pressure failure over time. The product complies with international safety standards for gas handling and pressure control.
