Emerson Fisher M95 Series Pressure Regulator High Performance Industrial Gas Pressure Reducing Regulator

The Fisher™ MR95 Series pressure regulators are direct-operated, high-performance devices engineered for precise pressure control in a wide range of fluid services. Available in both pressure-reducing and differential-pressure configurations, these regulators deliver reliable outlet pressure stability for liquids, gases, air, and steam. Designed for easy installation and long service life, the MR95 Series is the ideal choice for general industrial applications requiring accurate, repeatable pressure regulation.

• Wide outlet pressure range from 2 to 400 psig (0.14 to 27.6 bar)
• Pressure-reducing (MR95L/H/HP/HT) and differential (MR95LD/HD/HDP) models
• Body sizes from 1/4 NPT to 2 in. / DN 50
• Multiple body materials including gray cast iron, steel, stainless steel, Monel®, Hastelloy® C, and aluminum-bronze
• Superior shutoff: Class VI (elastomer seats) or Class IV (metal/PTFE) per ANSI/FCI 70-3-2004
• API 614 compliant constructions and sour-gas service options (NACE MR0175/ISO 15156)
• FDA, USP Class VI, and ADI-free EPDM elastomers available for clean-service applications
• High-temperature capability up to 650°F / 343°C (MR95HT models)

Ideal for wash tanks, small heaters, fuel and oil lines, air supply systems, test fixtures, sterilizers, and any process requiring precise pressure control in liquid, gas, or steam services.

Q: What is the difference between pressure-reducing and differential models?

A: Pressure-reducing models (MR95L/H/HP/HT) control downstream outlet pressure, while differential models (MR95LD/HD/HDP) maintain a constant pressure difference between a loading supply and the outlet.

Q: Are MR95 regulators suitable for sour gas service?

A: Yes—optional materials fully comply with NACE MR0175-2002, MR0103, and ANSI/NACE MR0175/ISO 15156 standards.

Q: Do I need external overpressure protection?

A: Yes, if actual inlet pressure exceeds the safe working pressure of downstream equipment.
