Type ED
Pressure Reducing Regulator:

The ED Series regulator is applied to over 85% of the pressure reduction needs for steam, air, gasses, water and other liquids. Four pilots with nine spring pressure ranges provide reduced pressures from 15 inches vacuum to 350 psi.

Type EQ
Back Pressure Regulator:

The EQ Series provides modulated back pressure control to retain pressure and/or prevent over pressure. Five pilots with eleven spring pressure ranges provide back pressure control from 1 to 350 psi.

Type EN
Differential Pressure Regulator:

The EN Series controls a system pressure above or below another process variable and ensures control accuracy within + or - 1 psi. Seven pilots with four spring pressure ranges provide differential pressures from 3 to 150 psi.

Type EP
Pump Governor:

The EP Pump Governor controls steam driven pumps so as to maintain an average discharge pressure regardless of changes in the load. Four pilots with five spring pressure ranges provide constant pump pressures between 30 inches of vacuum to 2000 psi.

Type EFD
Load Allocating Pressure Regulator:

When total system demand exceeds supply, the Type EFD permits prioritized load allocation. As the system recovers, less essential loads are restored.

Type D50
Direct Pressure Reducing Regulator:

A rugged, industrial grade, all purpose, high capacity, direct operated design available in 316 stainless steel 1/2-1 inch, bronze 1/2 and 3/4 inch, and cast iron 1/2-2 inch. Used where first cost and/or space limitations are a primary concern. Reduced pressure ranges from 3 to 140 psi.
