High-quality refrigeration valves for demanding applications

We offer an extensive range of PriWO refrigeration valves that have been developed for various applications in refrigeration technology.

Robust housing

Our refrigeration valves are characterized by their robust construction. The housings are made of durable brass as standard, but we can also offer you stainless steel versions on request.

2/2-way valves

Our refrigeration valves are designed as 2/2-way valves, which means they have two connections and two switching positions.

Individual functionality

Depending on the application, our refrigeration valves can be used in either “normally closed” (NC) or “normally open” (NO) operating mode. This flexibility allows you to optimally adapt the valves to your individual requirements.

Servo-controlled precision

The valves are servo-controlled, which ensures precise and reliable flow control.

Technical specifications

Our refrigeration valves are available in the following variants:

  • Pressure range: 0.05 to 130 bar

  • Nominal diameter: 5 to 25 mm

  • Kv value: 0.3 to 13

Advantages of PriWO refrigeration valves

  • High quality: The refrigeration valves are made of high-quality materials and are subject to strict quality controls to ensure outstanding performance and reliability.

  • Flexibility: Various options for housing material, mode of operation and nominal size offer high adaptability for different applications.

  • Precise control: The servo-controlled actuation allows precise regulation of the flow.

  • Wide pressure range: With a pressure range of 0.05 to 130 bar, the valves are ideal for a wide range of high-pressure applications.

Fast availability and comprehensive support

We ensure that the refrigeration valves are procured quickly and offer you fast delivery times.

Our experienced team is available to help you select the right valve and to assist you with any technical questions.

Areas of application

Refrigeration technology:
Refrigeration valves are used in air conditioning systems, refrigeration systems, cold stores and other refrigeration systems as well as in heat pumps.
