CASTEL INTRODUCES 34-E HIGH-PRESSURE VALVES FOR CO2 SYSTEMS
Castel has launched its new 34-E series of high-pressure electronic valves, developed for transcritical CO₂( R744) refrigeration systems. Designed for performance and environmental sustainability, the 34-E valves are suited for multiple functions including flash gas bypass, pressure regulation in gas coolers, and expansion control in evaporators. The 34-E valves integrate a control valve, filter, ball valve and charging port into a compact unit. This integration simplifies installation and reduces the number of components required in the system. Key applications include pressure regulation in the suction line and optimised management of temperature and pressure, contributing to overall energy efficiency. Constructed to operate under pressures up to 140 bar, the valves are certified according to European Directive 2014 / 68 / EU( PED) and other international standards. Each unit undergoes individual leak and reliability testing to ensure safety in demanding transcritical CO₂ environments. The 34-E series is designed for ease of maintenance. Versions with integrated ball valves allow for quick servicing – such as filter cleaning or part replacement – without removing the entire valve. This feature minimises downtime and potential refrigerant leakage, enhancing system continuity and reducing long-term operational costs.
By supporting CO₂ refrigerants, the valves contribute to reduced environmental impact due to CO₂’ s low global warming potential. The robust design and high reliability make the 34-E series compliant with the highest industry safety and sustainability requirements.
