Available in virgin PTFE lining or electrostatically dissipative. Optional with full or hollow ball made of PTFE, usable horizontal und vertikal. The advantage is a flow without hindrance, because no parts of construction remain in space like other check valves. The ball disappears in the side, so that the full flow over the entire nominal diameter is possible. The program scope includes the nominal diameters from DN 25 – DN 100 in PN 10.
