Fi-sher 1098-EGR Pressure Reducing Regulator
The Fi-sher 1098-EGR is a pilot-operated pressure reducing regulator designed for accurate and economical pressure control across a range of industrial and commercial applications. It combines a main valve with a pilot to deliver stable downstream pressure regulation, including performance at low differential pressures.
Product Overview
This regulator is suitable for natural gas distribution systems, fuel gas supply to boilers, furnaces, ovens and mixers, as well as large commercial or industrial facilities. It can also be applied in plant air and certain liquid services. Key advantages include the ability to control accurately at pressure differentials as low as approximately 1 psid (70 mbar d), precise pressure control, and reliable operation under varying flow conditions.
