Diaphragm-Type Pressure Relief / Regulating Valves. Inlet body is nylon; bonnet is aluminum. Flow rate to 56 GPM for ½″ and 70 GPM for ¾″ valve. 8460-*-50 uses stainless steel springs while 8460-* uses steel springs - responsive to the pressure range of each valve. Extra large passages to handle full flow from supply line.

Downstream Pressure Regulating Valve is self contained, self Operated control device, which automatically reduce a higher inlet pressure to a steady lower downstream pressure regardless of changing flow rate and varying inlet pressure. It utilizes energy from the controlled system. The regulator operates on the simple principal of force balance.
