Shacman X3000 X5000 Dual Fuel Tank Changeover Valve Assembly DZ91189553150

The DZ91189553150 Fuel Tank Changeover Valve Assembly serves as the central switching hub for dual-tank commercial vehicle fuel management. By regulating fuel flow via cab-mounted switch inputs, this Shacman dual tank selector valve switches both the engine suction line and fuel return line simultaneously, ensuring proper fuel draw and balanced fuel distribution.

Manufactured in ISO9001-certified facilities using high-density alloy valve body castings and diesel-resistant elastomeric seals, the DZ91189553150 valve resists continuous exposure to diesel fuel, bio-diesel blends, and severe chassis vibration. Replacing a jammed, leaking, or electrically failed selector valve with a brand-new DZ91189553150 unit restores seamless tank switching, prevents fuel starvation, and protects the high-pressure injection pump from air suction locks.

Technical Specifications

Key Features and Benefits

• Dual Circuit Synchronous Switching: Simultaneously redirects both supply and return fuel lines between tanks, preventing fuel overflow into a single reservoir.

• Fuel-Resistant Seal Integrity: High-grade internal gaskets and seals resist breakdown from diesel fuel additives, paraffin buildup, and temperature fluctuations.

• Heavy-Duty Solenoid Actuator: Rapid-response electric solenoid ensures clean port switching under constant fuel line priming pressure.

• Direct OEM Mounting: Designed strictly to factory specification DZ91189553150 for exact bolt-pattern matching and direct coupling to standard fuel line fittings.
