ตัวแทนจำหน่าย Fisher EZL Series | Pressure Reducing Regulator for Low Pressure Applications ในประเทศไทย
The Fisher EZL Series regulators are high-performance, pilot-operated, pressure-balanced, soft-seated regulators engineered for precision and durability. Designed specifically for natural gas distribution systems—including district regulator stations and commercial or industrial meter sets—they offer smooth, low-differential operation, tight shutoff, and extended service life.
Features
Ideal for Low Differential Pressure Applications
• Accurately controls downstream pressure at differentials as low as 2.9 psid (0.2 bar d), making it well-suited for low-pressure systems.
Bubble-Tight Shutoff
• A combination of a knife-edged metal plug and a soft seat ensures leak-free shutoff, making the EZL Series ideal for applications requiring positive shutoff, including dead-end systems.
Zero Atmospheric Bleed
• The pilot-operated design eliminates continuous gas bleeding to the atmosphere—100% of bleed gas is redirected to the downstream system, reducing emissions and operational waste.
Simplified In-Line Maintenance
• A top-entry design allows for quick inspection, cleaning, and replacement of trim components without removing the regulator from the pipeline.
Stable and Precise Pressure Control
• Delivers accurate downstream pressure control even with fluctuations in inlet pressure or load changes.
Travel Indicator
• Enables easy in-service diagnostics and troubleshooting by visually indicating valve plug movement.
Full Pressure Rating Capability
• Designed with equal inlet and outlet pressure ratings of 290 psig (20 bar), allowing for easier regulator selection and eliminating the need for special startup or shutdown procedures.
Integrated Slam-Shut Option
• The Type EZLOSX configuration includes a slam-shut mechanism that automatically interrupts gas flow in the event of an overpressure or underpressure condition, enhancing safety in critical systems.
