Wax-based thermostatic valves have been used for years to regulate jacket water, lube oil and LT cooling systems. But over time, worn thermostats, fluctuating temperatures and high leakage rates can affect engine performance and increase fuel consumption. Clorius Controls’ electrically actuated low leakage control valves offer a modern plug-and-play alternative for stable temperature control in all operating conditions. Replace outdated wax or AMOT B valves with the G3FM-ULL valve and controller package, and upgrade your cooling system with higher efficiency, faster warm-up time and minimal maintenance without hot work or class recertification.

For many years, wax-based thermostatic valves have been used to regulate jacket water, lube oil and LT cooling systems. But as engines age, these mechanical solutions often struggle to maintain the stable temperature needed for efficient and reliable operation. Fluctuating or low engine temperature, high leakage rates and worn thermostats can all reduce performance, increase fuel consumption and add unnecessary stress to critical engine components. Clorius Controls’ electrically actuated low leakage control valves offer a modern alternative: a compact plug-and-play solution that delivers stable temperature control in all operating conditions. By replacing outdated wax or AMOT B valves with our G3FM-ULL valve and controller package, you upgrade your cooling system with higher efficiency, faster warm-up time and minimal maintenance without hot work or class recertification.

Cut emissions where it matters most: in port Boiler runtime in port = wasted fuel and higher emissions. Solution: Ultra Low Leakage Valve ✅ Ultra-low leakage (<0.01%): Ensures the HT circuit stays closed during port calls ✅Reduced boiler runtime: Lowers fuel consumption and CO₂ output ✅Annual savings (expected): 30–60 tons of fuel per vessel A practical step towards more efficient shipping.

Upgrade your HT cooling system with the Ultra Low Leakage Valve from Clorius Controls. An engineered retrofit solution that keeps your cooling circuit stable and supports consistent engine operation under all conditions. Built for reliability and smooth installation.

Fluctuating or low engine temperatures and high leakage on existing valves can increase fuel consumption and operating costs. ➡️ ⚡ Converting thermostatic wax controls to electric control valves helps you achieve a higher and more stable engine temperature, supporting better fuel economy and more efficient operation of older engines.

Operating costs on board are directly affected by maintenance, fuel consumption and system efficiency. By replacing manual steam valves with automated control, operators can improve temperature stability and reduce unnecessary energy use. The Clorius Steam Control Valve offers a fast retrofit installation and proven reliability, helping shipowners achieve more efficient operations and better cost control.
