  • Masoneilan 172 Series

    Spring loaded, Direct Operated, Pressure Reducing Regulator

    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.

    General features:

    • Flow to open design
    • 9 to 14 different Cv ratings for each size to assure high accuracy of regulation
    • Metal or Sot Seat constructions
    • Internal pressure sensing (external on request)
    • Different face to face dimensions available
    • Wide range of actuator sizes according to the requested regulation range
    • Elastomeric or metal (316 st. st.) for fluid and application compatibility
    • Fully sealed construction available (suitable for dangerous medium; ATEX compliant)
    • Balanced construction available for high pressure drops
