Figure 1. 627 Series Commercial/Industrial Regulator

The 627 Series commercial/industrial regulator is a large capacity, high-pressure unit for use in conjunction with S302G or S202G Series regulators. It can also be used on Final-Stage service. A 1805 Series relief valve is recommended to prevent excessive build-up in the downstream line.

The diaphragm case and/or regulator body on the 627 Series can be rotated in any of four positions to allow installation in locations with limited space.
