The Spence Engineering E main valve comes in a variety of pressure classes and designs. The cast iron series of valves cover the full range of steam pressure regulation needs. When paired with a pilot operator, the valve requires a bends and fittings kit to connect the correct operator to the main valve. Here you will find the bends and fittings kits used for single pilot, double pilot, integral pilot, and P125 trip stop pilot operators. The kits are based upon valve size and application.
