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
