Common questions on this part
A standard wafer valve has a thin body without full flanges, meaning it relies entirely on the compression of long through-studs. In buried water lines or high-thrust pump headers, thermal expansion or water hammer can cause wafer valves to shift or leak. The 4M-DFW-ECO has dedicated flange rings with through-holes that provide rigid, immovable mechanical anchoring to mating pipe flanges.
Yes. The standard EPDM liner is manufactured from food-grade and drinking water compliant compounds that do not impart odor, taste, or chemical leaching into municipal potable water supplies.
STARNEX supplies 4MATIC butterfly valves on order with standard factory dispatch. Official KRA E-TIMS tax invoices, dimensional certified drawings, and hydrostatic test reports are provided with all commercial orders.
