Danfoss 068Z3209 TXV

Engineered for professional refrigeration and air conditioning applications, the Danfoss 068Z3209 is a high-performance TEX 2 Thermostatic Expansion Valve designed specifically for R-22 refrigerant (and R-407C compatibility). This externally equalized valve features a 3/8" flare inlet and a 1/2" flare outlet, with a 1/4" flare external pressure equalization connection to compensate for evaporator pressure drops. Built with a durable brass body and a laser-welded stainless steel power head, it ensures reliable superheat control across a wide temperature range of -40°F to +50°F. The Danfoss TEX-2 TXV utilizes an interchangeable orifice system (sold separately), allowing technicians to field-adjust the capacity from 1/4 to 5-1/2 tons to meet specific system requirements. The 59-inch capillary tube and high-sensitivity sensing bulb provide rapid response to load changes, protecting the compressor from liquid slugging while maintaining optimal evaporator efficiency.

• Precise Superheat Regulation: Externally equalized design ensures stable performance in systems with high pressure differentials or distributors.
• Field-Service Versatility: Compatible with Danfoss orifice assemblies 01 through 06, enabling customized capacity matching for various cooling loads.
• Durable Construction: Features a corrosion-resistant brass body and a stainless steel bulb with a patented strap for superior thermal contact.
• Extended Operating Range: Suitable for a broad spectrum of HVACR applications including walk-in coolers, ice machines, and air conditioning units.
• Adjustable Static Superheat: Allows for fine-tuning on-site (standard setting is 7.2°F) to maximize system COP and efficiency.

• Does this include the orifice? No, the Danfoss 068Z3209 is a valve body only. The orifice must be selected and purchased separately based on the required tonnage.
• Can this be used for R-410A systems? No, this TEX-2 expansion valve is specifically calibrated for R-22 and R-407C properties; using it with R-410A will lead to improper metering.
• What is the benefit of external equalization? The 1/4" external equalizer line monitors evaporator outlet pressure directly, preventing the valve from "hunting" or closing prematurely due to internal pressure drops.
