Cold Oil
Bypass Cooler
Directs the primary flow around the cooler while the lubricant is below the transition range.
Wind turbine application
Wind Turbine Lubrication Temperature Control
Thermostatic control valves regulate cooler and bypass flow as gearbox lubricant temperature changes, without external electrical power.
System function
Temperature-driven routing for gearbox lubrication and cooling.
A temperature-sensitive, replaceable thermal element moves the valve mechanism as lubricant temperature changes. The valve automatically directs flow between cooler and bypass paths, helping the lubrication circuit respond to cold start, transition and hot-oil conditions.

Transition Range
Modulated / Mixed Flow
Divides flow between the bypass and cooler paths as the thermal element moves through its operating stroke.
Hot Oil
Flow Through Cooler
Directs the primary flow through the oil cooler after the lubricant reaches the upper operating region.
Engineering inputs
