Expansion Valves

Expansion Valves

TR 6 thermostatic expansion valves have been designed and developed with features especially for use in applications such as residential air conditioning systems, split systems, roof top units, heat pumps, light commercial air conditioning systems and chillers.

The hermetic tight design meets environmental demands for today and the future. The TR 6 program is available for R22 and R410A, and models for other refrigerants can be produced to order.

The TR design incorporates a hot-pressed brass body with the entire power element, including the capillary tube and bulb, fabricated from stainless steel. The valves are supplied as standard in straightway versions with fixed orifice and with external equalization. They can be delivered with or without internal check valve and with external superheat adjustment spindle for field retrofit. All valves are designed with balanced port to reduce the influence from varying condensing pressures.
