Masoneilan 172 Series

The Masoneilan 172 series are spring loaded direct-operated, pressure reducing regulators. Their main function is to regulate the outlet pressure. They are available in ½” to 2” (DN15 through DN50) body sizes and can be supplied with a wide range of different end connections. The “bolted” flanged design provides flexibility to meet custom face to face dimensions as required, simplifying replacement of existing units. These regulators have a compact design and durable construction to withstand harsh conditions while being easy to install and to maintain.
