TUC/TUCE Thermostatic Expansion Valve
Brand: Danfoss
The TU series of thermostatic expansion valves is specifically developed for soldering into hermetic refrigeration systems.
The TU is made of stainless steel and therefore is well-suited to refrigeration systems for aggressive environments and for the food industry.
Danfoss also offers a wide range of options that makes possible countless valve combinations.
Differentiating Features: Stainless steel
- High body strength
- High corrosion resistance
- Highly vibration-resistant, flexible capillary tube
40% Reserve Capacity Over Nominal Rating
- Reduces pulldown time after defrost compared to conventional TXV's
Bi-metal Connections
- Fast and easy soldering without the need for a wet cloth
Precision Port Design
- Four major features contributing to superior repeatable performance over an extended valve life: Laser-welded power element insures diaphragm's structural integrity and lengthens life
- Precision-machined push-rod and bushing avoid the need for a packing gland
- Free-floating push-rod is self-aligning and eliminates binding. Precision-machined cone and orifice accurately meter refrigerant under all operating conditions
Stainless Steel Capillary Tube
- Tolerates more bending for easier installation and longer life
- Greater resistance to vibration during operation
Stainless Steel Bulb
- Self-aligning for fast and easy installation; secures with a single strap or Quick Clip
- More contact surface for better heat transfer
Built-in Strainer
- Angleway valve body: Unique 80 mesh strainer design capable of retaining more than twice the amount of dirt compared to that of a conventional design without restricting flow
- Straightway valve body: 100 mesh strainer
Compact Design
- Small footprint and light weight for compact installation
Laser Engraving
- Durable positive valve identification; no labels to peel off over time.
- Patented Superheat Adjustment Device
- Adjust with 5/32" Allen wrench
- Versions with optional self-cleaning bleed port available
Bi-flow Operation
- Optional Quick Clip bulb fastener For fast and easy installation
Standard Configurations are as follows
- Internal (TUC) or external (TUCE) equalization
- Fixed orifice and strainer
- Fixed superheat
- Straightway or angleway body
