Regulator Pengurang Tekanan Seri Fisher EZL untuk Aplikasi Tekanan Rendah

The Fisher EZL Series consists of pilot-operated, pressure-balanced regulators designed specifically for natural gas distribution and industrial applications. These regulators are engineered to excel in low-differential pressure environments, making them the preferred choice for district regulating stations and commercial meter sets. By utilizing a pilot-operated design, the EZL Series offers superior accuracy and capacity compared to direct-operated alternatives, ensuring a stable gas supply even during rapid load changes.

Ringkasan

Manfaat dan Keunggulan Utama

  • Low Differential Performance: The EZL Series is uniquely capable of maintaining accurate control at pressure differentials as low as 2.9 psid (0.2 bar d). This makes it ideal for systems where the available inlet pressure is only slightly higher than the required outlet pressure.

  • Bubble-Tight Shutoff: Featuring a precision knife-edged metal plug and a high-quality soft seat, the EZL provides a bubble-tight seal. This is a critical requirement for dead-end systems where any leakage during zero-flow periods could lead to dangerous downstream pressure buildup.

  • Zero Atmospheric Bleed: To prevent gas waste and environmental impact, the EZL utilizes a pilot system that bleeds 100% of the loading gas into the downstream piping. There is absolutely no bleed to the atmosphere during normal operation.

  • Easy In-Line Maintenance: The top-entry design allows maintenance personnel to inspect, clean, or replace all internal trim parts without removing the valve body from the pipeline. This significantly reduces labor costs and system downtime.

  • Precise Pressure Control: The pilot-operated mechanism ensures that downstream pressure remains stable and accurate, regardless of significant fluctuations in inlet pressure or sudden changes in gas demand.

  • Equal Inlet and Outlet Pressure Ratings: With a full pressure rating of 290 psig (20 bar) on both the inlet and outlet sides, the EZL simplifies system design and eliminates the need for specialized startup or shutdown procedures typically required for regulators with lower outlet ratings.

  • Visual Travel Indicator: Every EZL comes equipped with a visual travel indicator. This feature simplifies in-service inspections and allows for rapid troubleshooting by showing the actual position of the main valve plug.

  • Optional Integral Slam-Shut: The Type EZLOSX configuration includes an integral slam-shut device. This safety feature automatically interrupts the gas flow in the event of an overpressure or underpressure condition, providing an extra layer of protection for downstream assets.
