Fisher Type EZR | High-Capacity Pilot-Operated Relief and Backpressure Control

The Fisher Type EZR is a versatile, pilot-operated regulator engineered to function as either a high-performance relief valve or a backpressure regulator. Widely utilized in city gate stations, district regulating stations, and industrial facilities, the EZR is designed to handle "dirty" gas service while providing exceptionally quiet operation and a bubble-tight shutoff. Its pressure-balanced design and specialized cage architecture make it a top choice for critical overpressure protection.

Ringkasan

Manfaat dan Keunggulan Utama

  • Quiet Operation: The EZR series features a standard cage design that provides best-in-class noise reduction. It typically operates 6 to 8 dBa quieter than comparable flexible element regulators, often eliminating the need for downstream silencers or heavy insulation.

  • High Capacity: The streamlined flow path is engineered for maximum throughput. Unlike many competitors, Fisher products are laboratory tested to ensure that 100% of the published flow capacity is usable in real-world installations.

  • Superior Debris Protection: The revolutionary flow path within the cage is designed to minimize damage from entrained particles. Additionally, a standard stainless steel inlet strainer prevents larger debris from reaching and damaging the diaphragm.

  • Long-Life Diaphragm Design: The field-proven diaphragm utilizes layered fabric and a molded shape with a raised bead edge. This construction significantly increases strength and durability, extending the interval between required maintenance cycles.

  • Tight Shutoff: A metal plug design is used to deflect particles away from the seating area. This protects the diaphragm and ensures a reliable, tight seal even in systems with significant particulate matter.

  • Integrated Travel Indicator: Every EZR includes a visual travel indicator. This simplifies in-service inspections and allows technicians to troubleshoot system performance without taking the regulator out of the line.

  • Operational Versatility: The EZR body is highly adaptable. By simply swapping the relief pilot for a pressure-reducing pilot, the unit can be converted from a relief/backpressure valve into a standard pressure-reducing regulator.

Properti Teknis

  • Operation: Pilot-operated for high accuracy and rapid response.

  • Configuration: Can be used for relief (overpressure protection) or backpressure (maintaining upstream pressure).

  • Body Sizes: Available in a wide range of sizes, typically from NPS 1 through NPS 8 (DN 25 through DN 200).

  • Pressure Ratings: Designed to meet standard flanged pressure ratings for utility and industrial gas headers.

  • Temperature Range: Suitable for a broad range of standard and low-temperature gas services.

Bidang Aplikasi

The EZR is a “workhorse” for gas utilities and large-scale industrial users who require high capacity and low noise. It is particularly effective in stations located near residential areas where noise pollution is a concern.

Industri Primer dan Pemanfaatannya:
  • City Gate and District Stations: Providing primary or secondary overpressure protection for municipal gas grids.

  • Commercial/Industrial Plants: Acting as a backpressure regulator to maintain stable upstream pressure for process equipment.

  • Dirty Gas Service: Managing natural gas streams that contain sand, scale, or other small particulates.

  • High-Flow Transmission: Relief protection for high-volume pipelines where massive flow must be managed during a surge.
