This pilot valve integrates all the principal functions of a two-way control circuit in a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot opens as upstream pressure rises above the set point. An integral restriction acts as an upstream flow restrictor enabling smooth valve closing and simplifying the control circuit.
