The Danfoss Flomatic Corp. announces a new product enhancement of its Enviro Check Valve Series 80E and 100E. The new check valves are especially designed for submersible well water pumps, where the well water may initially contain clay and silt introduced during the well drilling process. They have been engineered to handle the finer particles of the aquifer around the well screen prior to putting the well into service without sticking open or closed. The new valve seat modification allows the valve to function with sand/silt solution concentrations up to 5 percent by volume in the well water. The unleaded Enviro series comes in a variety of sizes and configurations — the 100E is shown here. Danfoss Flomatic Corp.
