MAG

MAGThe MAG is a fast-acting tilting disc valve offering fast response to flow change, tight shut-off, low pressure loss, and excellent flow characteristics. This check valve is often used in steam or gas applications to protect the steam turbine or compressor against backflow.
Numerous installations in gas cracking units confirm high reliability in critical services.
