Category Specification
Model MR98L
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 (e.g., a model might be ordered for a range of 50-150 psig). The exact range must be confirmed by the spring installed.
Maximum Inlet Pressure Limited by the main regulator body, but the pilot itself is typically suitable for high pressures common in gas transmission, often up to 1440 psig (100 bar) or more.
Relief Capacity The flow capacity is determined by the size of the main regulator valve body on which it is installed and the orifice in the pilot. It is designed to handle the full flow capacity of the main regulator in a failure scenario.
Supply Self-powered by the process pressure. No external power required.
Materials of Construction Body: Cast Steel or Ductile Iron (for high-pressure service).
Internals: Stainless Steel.
Port Connections Typically 1/4" or 1/2" 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).
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).
