Diamond Series 3 Pressure Relief Valves

The new Series 3 Pressure Relief valve uses elements of the DPL single and double seat valves to produce a full bore, self draining device ranging in size from 1-4”. Available in manual and actuated format, the Series 3 valves have a tamper-proof pressure setting mechanism which can be adjusted in-line. The valve can be disassembled for servicing without affecting the factory pressure setting.
