The outlet is one size larger than the inlet to ensure high discharge flow rates. It has a separate seal seating from the diaphragm with a cover that is made from OT58 brass. Available in a variety of sizes to suit most installations, it also has a pressure range from 2.5 bar to 5.0 bar with the response pressure indicated on the twist cap.
