Asosiy afzalliklari va afzalliklari
-
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.

-
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.
