Reference is made to our Principals’ new LLGG temperature control valve that satisfies ANSI (American National Standards Institute) IV Requirements for 0.01% leakage rate.

G Valve

The G Valve along with relevant supporting equipment are designed for the control of fluid temperature by ‘diverting’ or ‘mixing’ control techniques.
The valves can be used for fresh and sea water, most lubricating oils and other liquids.
The compact construction of the G Valve enables unobstructed, full-bore flow, thus minimizing pressure losses.

Benefits of the G Valve

• Eliminates bypass leakage
  • Reduced cooling circuit capital costs and operating costs
  • Maximized cooling to support higher engine output power
  • Maximized cooling to operate in higher ambient temperatures
  • Increased fuel efficiency and reduced emissions with improved LT temperature control

• Eliminates leakage to cooler
  • Faster engine warm up times
  • Minimized energy waste during pre-heat
  • Minimized heat loss at low engine load
• High efficiency heat recovery

The LLG – Engine Field Trial/ Case Study

• 3000 running hours trial
• Air cooled application in high ambient temperatures
• Standard G-Valve upgraded to LLGG
• Upgrade increased cooling capacity by 4°C
• Improved charge air temperature control resulting in significant fuel savings
