Compressor valves

Wide range: Our comprehensive range includes numerous valve types for connecting to compressors and they are suitable for use with almost all refrigerants, including ammonia, propane and CO2. Our solutions are as diverse as your requirements. From transport air conditioning to applications in industrial refrigeration systems, we always have the right valve design for your refrigerating circuit.
They meet the standards of DIN EN 12284, conform to the Restriction of Hazardous Substances Directive 2002/95/EC, UL, ASME.

Line valves

Works best under pressure: With the new AWA line valves, we offer products that enable your system to work at the desired pressure. For example, our angle valves are extremely durable thanks to their brazed steel housing and galvanic surface protection. Due to flexible inlet and outlet combinations and high pressure ratings, they can be used in almost every system. We also manufacture custom line valves based on your requirements.

FAS products

A brand with a profile: Ever since we integrated the refrigeration valves manufacturer FAS into AWA in 2002, our product range has been even more diverse. The FAS brand has its own unique focuses.
One of the highlights is the combined check and shut-off valve, which can be used to regulate refrigerant mass flow rates and enhances the reliability of refrigeration systems. They are highly flexible, thanks to the large number of connection types – solder, flare, weld or soldering flange. Quality is our main principle. That’s why the check valves are absolutely tight in accordance with DIN 8513 – and we test every single valve as part of our quality assurance.
If one of the check valves should show signs of wear after long-term use, the internal parts can easily be exchanged. The check valves are also designed to meet the standards of DIN EN 12284 and they conform to the Restriction of Hazardous Substances Directive 2011/65/EU.


The subtle difference: True quality can be seen in the details. With our wide range of accessories, we can solve every system problem. For example, AWA sight glasses allow for visual checks of fill levels in vessels, receivers and crankcases. And we deliver our sight glasses in a wide range of variants with flange, screw-in and Rotalock connections. Due to our fittings and adapters, we can connect different connectors. This way, even different models of refrigeration systems can be filled with ease – thanks to our service valves.
