The Type EZH regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in high pressure natural gas transmission/city gate stations, large capacity distribution systems, and power plant feeds. They provide smooth, reliable operation, tight shutoff and long life.

Available Configurations

Type EZH:  Pilot-operated pressure reducing regulator for low to high outlet presure.

Type EZHOSX: Type EZH with a Type OS2 slam-shut device for overpressure or overpressure and underpressure protection.
