      Epoxy painting suitable for potable drinking water applications

      The dual plate check valves wafer type are a compact kind of check valve. With a small face to face length and being wafer type, these dual plate check valves can be mounted directly between flanges and in accordance to many standard connections. The body is made in one piece only, in cast iron with disc in ductile iron, stainless steel or Al-bronze and spring in stainless steel, these parameters allow the dual plate check valves to be applied for several applications. The automatic mechanism of plate opening grants low water losses, and the spring avoids fluid hammer effect. Epoxy coated inside and outside, these check valves are suitable for potable water.
