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).
