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.

Product Overview

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 optimized 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.

Maintenance and Operational Efficiency

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 minimizes downtime and potential refrigerant leakage, enhancing system continuity and reducing long-term operational costs.

Environmental and Regulatory Compliance

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.

“Castel continues to innovate to provide cutting-edge solutions in the refrigeration industry for a greener future,” the company stated.
