Original Fisher MR98 Series: Versatile Direct-Operated Backpressure and Relief Regulators from China Supplier YUNRUI

Siri Fisher MR98: Pengawal Selia Tekanan Balik dan Pelega yang Dikendalikan Secara Langsung Serbaguna

The Fisher MR98 Series is a highly adaptable line of regulators specifically designed for backpressure or relief applications. Unlike standard reducing regulators, the MR98 series opens on increasing upstream pressure to maintain a constant backpressure or to protect systems from overpressure. Whether handling liquid, gas, air, or steam, the MR98 provides high-capacity performance in a compact, direct-operated design.

Gambaran Keseluruhan

Faedah dan Kelebihan Utama

  • Unmatched Versatility: A true multi-purpose platform suitable for backpressure, bypass, and relief tasks across liquid, gas, and steam services.

  • Differential Pressure Capability: Specialized models (MR98LD, MR98HD, and MR98HHD) utilize pressure loading to maintain precise differential pressures or allow for remote setpoint adjustments.

  • Large Turndown Ratio: Maintains stable and accurate control even during wide variations in system flow, preventing pressure surges.

  • High Pressure Performance: Capable of managing set pressures up to 400 psig (27.6 bar), making it robust enough for heavy-duty industrial steam and fuel systems.

  • Tight Shutoff: When equipped with elastomer seats, the MR98 ensures a bubble-tight seal to prevent leakage and maintain system integrity when the relief point is not reached.

  • Temperature Resilience: Features standard graphite gaskets for high-heat steam service, with specialized construction options available for Arctic and Cryogenic environments.

  • Sanitary Ready: Offers FDA, USP Class VI, and ADI-free EPDM wetted elastomers for sensitive applications in the pharmaceutical and food industries.

  • Simplified Maintenance: The top-entry design allows for fast inspection and servicing of internal components without the need to remove the valve body from the piping.

Hartanah Teknikal

  • Direct-Operated Models: Types MR98L (low pressure), MR98H (high pressure), and MR98HH (extra-high pressure) are spring-loaded for fast, reliable response.

  • Pressure-Loaded Models: Types MR98LD, MR98HD, and MR98HHD utilize a loading pressure on the diaphragm for remote or differential control.

  • Body Sizes: Available in 1/4 inch to 2 inches (DN 6 to 50).

  • End Connections: Offered in NPT, SWE, and various flanged configurations (ANSI or DIN).

  • Material Selection: Available in Carbon Steel, Stainless Steel, and specialty alloys for corrosive chemical or special service environments.

Bidang Aplikasi

The MR98 Series is the go-to “safety valve” for maintaining constant upstream pressure. It is commonly found in pump bypass loops, steam injection systems, and nitrogen purging stations.

Industri Utama dan Kegunaan:
  • Oil and Gas: Nitrogen purging, fuel line backpressure, and pneumatic supply protection.

  • Power and Steam: Steam tracing, steam injection, and boiler feed water relief.

  • Life Sciences: Autoclaves, sterilizers, and clean steam backpressure control.

  • Manufacturing: Wash tank pressure maintenance and cooling water bypass.

  • Process Chemicals: Corrosive chemical relief and test fixture pressure regulation.
