Patent ID: 8689832

Claim:
A fluid flow control device, comprising: a body having a inlet connection, an outlet connection, and a discharge port; and a booster module disposed within the body comprising a control element and an actuator element having a manifold, a first diaphragm, a second diaphragm, and a noise-reducing trim element, the noise-reducing trim element comprising an outer cylinder portion, the booster module having a supply path extending between the inlet connection and the outlet connection and an exhaust path extending between the outlet connection and the discharge port, the manifold comprising a seating member having a plurality of passageways, the seating member extending through a central portion of at least one of the first and second diaphragms, and the noise-reducing trim element being operatively coupled immediately adjacent to the discharge port and having a plurality of passageways arranged to distribute a fluid flow therethrough to the discharge port via the exhaust path into a plurality of fluid jets to substantially inhibit jet flow interaction at the discharge port.
