The Spence Engineering E2 main valve is designed for low pressure applications. 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, and integral pilot operator applications. The kits are based upon valve size and application.
