Abstract
An assembly for reducing excess piping pressure in a fluid distribution system. The assembly includes a fluid regulator including a body defining an inlet, an outlet, and a fluid passageway between the inlet and the outlet, a first control element movable relative to a valve seat in the fluid passageway to control fluid flow therethrough, a valve stem coupled to the first control element, and an actuator assembly operatively coupled to the valve stem to control a position of the first control element. The assembly also includes a solenoid valve coupled to the fluid regulator at a position upstream of the outlet, the solenoid valve adapted to receive a control signal indicative of zero demand downstream of the fluid regulator, and having a second control element that is movable, responsive to the control signal, from a first position to a second position to reduce fluid flowing through the fluid passageway.
