1V711606242
Technical Parameters
Parameter Value / Description
Fisher Model Number 1V711606242
Type Pilot-Operated Pressure Reducing Regulator
Valve Size (Port Size) 2 inch (2")
Orifice Size Typically 2 inch (Depending on trim)
End Connections Flanged (RF or RTJ are common)
Pressure Rating (ANSI Class) Class 300 (or as specified)
Body Material Carbon Steel (e.g., WCB)
Trim Material Standard Trim (e.g., 304 Stainless Steel)
Main Diaphragm Material Typically Nitrile (Buna-N) or other elastomers for standard service.
Pilot Diaphragm Material Typically Nitrile (Buna-N)
Max Inlet Pressure (P1) Varies with body rating, e.g., up to 750 psig (51.7 bar) for Class 300.
Outlet Pressure Range (P2) Depends on the specific spring range installed.
Example Spring Ranges: 3 to 9 psig, 8 to 30 psig, 20 to 60 psig, etc.
Temperature Range Standard: -20°F to +150°F (-29°C to +66°C) with standard elastomers. Higher temperatures with special materials.
Pilot Connection Size 1/2 inch NPT
Leakage Class Class IV (Metal-to-metal seat) or Class VI (Soft seat) depending on trim.
FISHER MR95L
Category Specification
Model MR95L
Type Pilot-Operated, Spring-Loaded Monitor or Relief Pilot
Function Overpressure Protection (Relief) / Backup Monitor
Setpoint Range The setpoint is field-adjustable. The specific range is determined by the spring range installed inside the pilot. Common ranges for the 95L series are lower than the 98L, for example, 5-50 psig or 10-100 psig. The exact range must be confirmed by the spring installed.
Maximum Inlet Pressure Suitable for the pressure ratings of the main regulators it services, typically found in medium-pressure applications.
Relief Capacity The flow capacity is sufficient to handle the overpressure scenario for the main regulator it is protecting, determined by the orifice size in the pilot and the main valve size.
Supply Self-powered by the process pressure. No external power required.
Materials of Construction Body: Cast Iron or Aluminum (standard).
Internals: Stainless Steel, Brass.
Port Connections Typically 1/4" NPT for the sensing and control lines.
Temperature Limits Suitable for standard industrial ambient and process temperatures. Specific limits depend on the elastomers used (e.g., Buna-N standard).
