Product overview
Automatic thermal control for gearbox lubrication circuits.
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.
Configuration note
Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED INC confirms the controlled specification before order acceptance.
Key features
- Automatic temperature-driven routing between bypass and cooler circuits
- Replaceable thermal element / thermal actuator
- No external electrical power required
- Model-specific 40–55°C or 45–60°C operating range
- Maximum flow up to 20 m³/h on the specified TVC models
- Phosphate-treated spring and housing surfaces
- Temperature-driven mechanical stroke
How it works
Temperature-driven routing between bypass and cooler circuits.
The replaceable thermal element responds directly to lubricant temperature and moves the valve mechanism without external electrical power.

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.
