EZL Series Pressure Reducing Regulator for Low Pressure Applications
The EZL Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in natural gas distribution applications such as district regulating stations and commercial/industrial meter sets. They provide low differential, smooth, reliable operation, tight shutoff and long life.
For overpressure or overpressure and underpressure protection, the Type EZLOSX is available with a slam-shut device.
