EXPANSIONTECH (44220-3)

OLAB ExpansionTech is the solenoid expansion valve designed for professional CO2 (R744) systems, combining fast installation, leak-proof sealing, and maximum internal cleanliness. Thanks to the FastLock CO2 connection, welding is no longer required—eliminating the risk of damaging seals and internal components during installation, while reducing time, cost, and operational complexity.

Sealing is ensured by OLAB-certified 100% PFAS-FREE EPDM O-Rings, winner of the Innovation of the Year award at ATMO Summit Europe 2024, located between both the body and nozzle and the body and sleeve. The sleeve, made of AISI 304 stainless steel, is laser-welded in-house at OLAB with dedicated technology to ensure durability and long-term sealing.

The valve body is made of yellow brass. The 36 mm coil, H-class (180°C), is UL-certified and rated IP67: full insulation is guaranteed by two O-Rings, top and bottom, protecting it from moisture and external contamination. An internal stainless-steel filter, fully inspectable, prevents even the smallest impurities from entering the system. The DN is equipped with a removable stainless-steel insert, interchangeable across the entire DN range.

ExpansionTech is fully inspectable and individually tested with OLAB’s 100% helium leak detection system. Each valve is marked with production date and serial number, ensuring complete traceability of performance data over time. The static pressure rating is 90 bar (1305 psi), the maximum MOPD is 37 bar (537 psi), and the operating temperature range is -50°C to +100°C (-58°F to +212°F). The valve complies with IP67 and UL 207 standards and is classified as a LOW-PFAS IMPACT component thanks to its exclusive use of OLAB-certified 100% PFAS-FREE EPDM O-Rings.
