Sustainable valve technology for refrigeration systems, heat pumps, and industrial applications
Our PriWO Refrigeration Valves
PriWO Refrigeration Valves for CO2 Refrigeration Systems and Industrial Refrigeration Technology
Today’s refrigeration systems operate at higher pressures, under stricter environmental regulations, and with increasing demands on energy consumption and operational safety. Our PriWO refrigeration valves were developed precisely for these applications. They control refrigerant flow in industrial refrigeration systems, heat pumps, and CO2 systems—where compact designs, high switching frequencies, and stable flow control are critical.
Our PriWO refrigeration valves are used worldwide in refrigeration systems, air conditioning systems, industrial cooling systems, and CO2 applications. Natural refrigerants such as CO2, in particular, create operating conditions that often push conventional valve technology to its limits.
PriWO Refrigeration Valves for High-Pressure Applications – Typical Challenges in Refrigeration Technology
Today, modern refrigeration systems must perform significantly better than they did just a few years ago. At the same time, operators face economic pressures and must comply with legal requirements such as the F-Gas Regulation.
Common challenges with refrigeration valves:
- High operating pressures in CO2 refrigeration systems
- sharp temperature fluctuations
- limited installation space
- high switching frequencies during continuous operation
- increasing energy consumption requirements
- sensitive refrigerant circuits
- Pressure surges within the system
- strict requirements for leak tightness
- Maintenance Costs Associated with Unsuitable Valves
- Fluctuating load conditions in heat pump systems
CO₂ refrigeration systems, in particular, operate at significantly higher pressure ranges than traditional HFC systems. At the same time, valves must operate reliably over the long term, even when subjected to thousands of switching cycles per day.
PriWO refrigeration valves for industrial cooling offer economic benefits
In industrial refrigeration systems, every watt of power consumption counts. At the same time, downtime and maintenance costs must be kept to a minimum.

FAQ – PriWO Refrigeration Valves for Industrial Refrigeration and CO2 Applications
CO2 refrigeration systems operate at significantly higher pressure ranges than conventional refrigeration systems. Our PriWO refrigeration valves were specifically designed for these conditions and are suitable for high-pressure applications up to 130 bar.
Despite their high switching capacity, servo-controlled refrigeration valves require only a small amount of electrical power. At the same time, they enable controlled switching operations and stable regulation of refrigerant flows.
Many refrigeration systems undergo thousands of switching cycles per day. High switching frequencies have a significant impact on wear, heat generation, and service life. Our PriWO refrigeration valves are designed for continuous operation with high switching frequencies.
Our refrigeration valves are used in a variety of applications, including CO2 refrigeration systems, heat pumps, air conditioning systems, industrial cooling, medical technology, and process cooling.
CO2 is considered a natural refrigerant and is not subject to the restrictions imposed on many synthetic refrigerants under the F-Gas Regulation. At the same time, CO2 enables energy-efficient and sustainable cooling systems.
Depending on the model, our PriWO refrigeration valves cover pressure ranges up to 130 bar. This makes them particularly suitable for industrial high-pressure refrigeration systems and CO2 systems.
The Kv value determines the valve's flow capacity. Proper sizing affects pressure drop, control performance, and energy consumption of the entire refrigeration system.
For the design, we consider the medium, pressure range, temperature, cycling frequency, and installation conditions. We then determine the valve size, Kv value, and actuation type appropriate for the application.
