Fisher Type 99: The Versatile Pilot-Operated Standard for Gas Distribution

The Fisher Type 99 is one of the most widely used pilot-operated regulators in the gas industry, known for its high capacity and extreme accuracy. By utilizing a pilot-operated design, the Type 99 provides a nearly flat pressure control curve, making it ideal for applications where downstream pressure must remain constant despite significant changes in inlet pressure or flow demand. Whether used in municipal distribution or large industrial fuel lines, the Type 99 delivers reliable, high-performance regulation.

Umumiy ko'rinish

Asosiy afzalliklari va afzalliklari

  • High Accuracy: The pilot-operated system ensures that the main valve responds to the slightest change in downstream pressure, providing much tighter control than standard direct-operated regulators.

  • No Atmospheric Bleed: The regulator utilizes a loading system that bleeds all pilot gas into the downstream piping, eliminating hazardous or wasteful emissions to the atmosphere.

  • High Inlet Pressure Capability: Engineered to handle robust upstream conditions, with the ability to manage inlet pressures up to 1000 psig (69.0 bar).

  • Excellent Low Flow Control: Unlike many high-capacity regulators that struggle at low demand, the Type 99 maintains stable and precise control even during minimum flow periods.

  • Tight Shutoff: Designed to provide a positive seal, preventing pressure creep in downstream systems during periods of zero flow.

  • Simplified Maintenance: The actuator and pilot can be easily accessed for service, and the standard O-ring seals on the guide bushing prevent pressure interference for more reliable operation.

  • Customization: The regulator is easily modified for special services, including different elastomer options for chemical compatibility or specialized trim for noise reduction.

  • Body Size: NPS 2 / DN 50.

  • End Connections: Available in NPT, CL125 FF, CL150 RF, CL250 RF, and CL300 RF configurations.

  • Pilot Options: Offers three distinct pilots (Type 61L, 61H, or 61HP) to cover a wide range of outlet pressure requirements from inches of water column to 100 psig.

  • Integrated Design: Features a Type 61 pilot integrally mounted to the actuator casing, reducing the risk of tubing leaks and simplifying the installation footprint.

  • Pressure Isolation: Standard O-ring seals on the guide bushing and valve carrier isolate the lower casing from outlet pressure fluctuations, ensuring the pilot only “sees” the true downstream pressure.

Qo'llanish sohasi

The Type 99 is a workhorse regulator used in large-scale gas systems where high capacity and precision are non-negotiable. Its versatility allows it to be used as a primary regulator in everything from city gate stations to industrial boiler rooms.

Asosiy sanoat tarmoqlari va ulardan foydalanish:
  • Natural Gas Distribution: District regulating stations and town border stations.

  • Industrial Energy: Fuel gas supply to high-capacity industrial boilers, furnaces, and kilns.

  • Commercial Gas Systems: Large establishments such as hospitals, universities, and shopping malls.

  • Plant Air Service: High-volume compressed air distribution and pressure control.
