Cold Oil
Bypass Cooler
Directs the primary flow around the cooler while the lubricant is below the transition range.
Thermostatic Valves
TVC / T1280
Automatic temperature control for wind turbine gearbox lubrication and cooling circuits, with a replaceable thermal element.

Product overview
The TVC / T1280 family is designed for wind turbine gearbox lubrication and cooling circuits. A temperature-sensitive, replaceable thermal element moves the valve mechanism as lubricant temperature changes, automatically directing flow between the cooler and bypass paths without external electrical power.
Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED INC confirms the controlled specification before order acceptance.
How it works
The replaceable thermal element responds directly to lubricant temperature and moves the valve mechanism without external electrical power.
Cold Oil
Directs the primary flow around the cooler while the lubricant is below the transition range.
Transition Range
Divides flow between the bypass and cooler paths as the thermal element moves through its operating stroke.
Hot Oil
Directs the primary flow through the oil cooler after the lubricant reaches the upper operating region.
