Series 69 Pressure Relief Valves

NON-CODE ADJUSTABLE LIQUID RELIEF VALVE, WATER RELIEF VALVE

 

Series 69 is an industry standard liquid relief valve used for pressure relief and by-pass.
Engineered and designed for heavy duty, industrial and commercial usages. A single piece bonnet to eliminate leakage while allowing for simple cleaning. Easy removable sealed hex-cap to adjust pressure.

Series 69

Liquid Relief ValvesSeries 69 Liquid Relief Valves are calibrated (set to pressure) based on a range of flow-rates (GPM) versus seat size and set pressure. Standard valve is set to pressure to achieve flow rate maximum and minimums within each set pressure range. See capacity chart for details.
