This animation illustrates how a standard Polychem chain and flight scraper system is assembled and installed.
The 106-PFC/206-PFC pressure modulation valve is a pressure-reducing valve with a special patented pilot that increases downstream pressure as flow increases. The PFC valve alters and controls pressure with flow to create virtually constant pressure at the critical pressure point in a system. It will also automatically adjust for distribution friction losses. This PFC valve will deliver consistent performance, as it has no electrical components and will not be affected should the valve chamber be flooded. This valve may be used wherever a standard PRV is installed.
