These control downstream pressure and require downstream over pressure protection when used with rupture discs.

Technical Parameters

• Operating Pressure: upstream up to 740 psig (51.0 bar) for high-pressure models; downstream up to 300 psig (20.7 bar)
• Temperature: –20 °F to +400 °F standard; up to +600 °F optional with graphite gasket
• Flow & Cv: Cv values available in bulletins; full port Cv for sizing safety relief
• Line Size & Connections: DN15–DN50, NPT or flanged (150# / 300#)
• Leakage Class: metal seats to class IV; composition seats to class VI
• Standards: require rupture disc as upstream or downstream protection
• Maintenance: replaceable trim, diaphragms; mechanical travel stops for diaphragm protection

Applications

• Oil & Gas: wellhead, storage, separator vessels
• Petrochemical: reactor systems, overhead lines
• Power/Municipal: steam boilers, condensate systems
• Cryogenic: with temperature-rated models (e.g. 1000HP LP) forming part of gas storage relief systems

Notable Features

• Wide pressure ranges: from ounces/in² to 740 psig
• Materials: broad compatibility for aggressive media
• High Cv capacity: large flow capability in compact regulators
• Diaphragm protection: travel stops prevent damage
• Serviceability: complete internal access via IOM manuals
