Solenoid operated valve for reducing excessive piping pressure in a fluid distribution system

A fluid regulator for reducing excess piping pressure in a fluid distribution system, the fluid regulator comprising:

• a regulator body defining a first inlet, a first outlet, and a first fluid passageway between the first inlet and the outlet;
• a first valve seat disposed in an orifice of the regulator body within the first fluid passageway, wherein the first valve seat defines a primary seating surface and a secondary seating surface, the primary seating surface defined between the orifice and the fluid outlet, and the secondary seating surface defined between the fluid inlet and the orifice;
• a first control element movable relative to the first valve seat to control fluid flow through the first fluid passageway;
• a first valve stem coupled to the first control element;
• an actuator assembly operatively coupled to the first valve stem to control a position of the first control element;
• and
• a solenoid valve carried by the regulator body, the solenoid valve adapted to receive a control signal indicative of zero demand downstream of the first outlet, the solenoid valve having a second control element that is movable, responsive to the control signal, between a first position, wherein the second control element is spaced from the secondary seating surface of the first valve seat and substantially outside of the first fluid passageway, and a second position, wherein the second control element engages the secondary seating surface of the first valve seat, such that the second control element reduces fluid flow from the first inlet to the first outlet.
