ODF Solder Expansion Valve – Interchangeable Orifice for AC,Balanced port TXV, R410A/R32/R22 compatible. Capacity up to 52 TR. ODF solder, flare, and Chatleff connections. Adjustable superheat, stainless steel power element. Max working pressure 46 bar.
Our Thermostatic Expansion Valve (TXV) regulates refrigerant flow into the evaporator by controlling superheat, ensuring maximum evaporator efficiency and protecting the compressor from liquid slugging. The balanced port design reduces the influence of varying condensing pressures, providing stable operation across a wide range of conditions.
Manufactured with a forged brass body and stainless steel power element, it resists corrosion and vibration. Available with adjustable or non-adjustable superheat, internal check valve options, and multiple connection types.
