106 / 206 / 306-PFC Pressure Flow Control (Modulation) Valve

The 106-PFC / 206-PFC / 306-PFC Pressure Flow Control Valve is a pressure reducing valve with a special (Patented) pilot that increases downstream pressure as flow increases.

The PFC valve controls the downstream pressure as a function of flow. This increased downstream pressure compensates partially for pipe friction and therefore maintains a relatively constant pressure at some remote location. The PFC valve will deliver consistent performance without any electrical components and is not affected by flooding. The valve can be used wherever a standard PRV is installed.

Please note that the downstream (controlled) pressure increases from low flow to selected maximum flow but reduces at flows higher than the selected maximum. This is due to the increased pressure drop of the orifice plate. If this reduction of the controlled pressure past the design maximum flow is a problem, contact us or your Singer® representative for an engineered solution.

• Reduces downstream pressure when demand is low to reduce leakage and pipe breaks
• Compensates for pressure loss in the pipe to keep a fairly constant pressure at a distant point. This reduces the pressure during low flow in most of the system
• Simple to set-up and adjust
• Maximum pressure increase can be limited by simple adjustment
• Pressure increase is adjustable
