Reliance 3/4″ x 1″ Female BSP 6.0 Bar Pressure Relief Valve

Details

A high capacity pressure relief valve to protect closed-circuit water heating systems from overpressure, made from hot pressed brass. 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 which 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. The valve size is determined by the heat output of the boiler as shown in the maximum heating capacity table on page 2.
