SINGER #106/206-PR-8761A low pressure control valve

Model #106/206-PR-8761A is a pilot operated low pressure, pressure reducing valve which is designed to automatically reduce a high inlet pressure to a lower outlet pressure. The valve will maintain a relatively steady dowsntream pressure regardless of fluctuations in the supply pressure or flow rate. During low pressure periods the valves bonnets vents directly to atmosphere, and only when teh nilet pressure increases, do the valve start to modulate.
