Hermetically tight expansion valve for today's and tomorrow's refrigerants
TR 6 thermostatic expansion valves are designed and developed for ducted split (US residential) air conditioning and light commercial air conditioning systems. With the TR 6 you get a hermetically tight design which meets the environmental demands of today and tomorrow and can be used for all fluorinated refrigerants.
The TR 6 design incorporates a hot-pressed brass body with the entire power element, including the capillary tube and bulb, fabricated from stainless steel. The valve is supplied as standard in straightway version with fixed orifice and external equalization.
The valve can be delivered with or without internal check valve and with an external superheat adjustment spindle for field retrofit. The TR 6 valve has a balanced port design to reduce the influence from varying condensing pressures.
Features and benefits
Compact size, hermetic design
Laser-welded power element for long service life and high pressure tolerance
Stainless steel capillary tube, for easy installation and vibration resistance
Adjustable or non-adjustable superheat for customer specific factory setting
Solder or mechanical connections
UL certified
