ADAPTER PLATES FLAP VALVES / MULTI-MANHOLES ADAPTER PLATES PRODUCT'S ADVANTAGES • Universal : fits on all circular manholes DN 800 à 1200 for the NORHAM flap-valves ranges. • Easy to install : installed in the manhole using mechanical anchors. • Highly resistant : made of fiberglass reinforced polyester or HDPE - EPDM seals. OPTIMUM SOLUTION FOR CIRCULAR MANHOLES FITTINGS & JOINTS

ADAPTER PLATES FLAP VALVES / MULTI-MANHOLES ADAPTER PLATES AREA OF USE The MULTI-MANHOLE ADAPTER FLANGE provides a suitable and optimal solution when a piece of flat surface or female connection (type flap-valve, penstock, regulator, ...) must be installed in a circular manhole. Thanks to its particularly studied geometry (patented system), the MULTI-MANHOLE ADAPTER FLANGE can be mounted indifferently in a manhole of DN 800 to 1200. Two standard ranges of MULTI-MANHOLE ADAPTER FLANGE are available: • the ARVN range for end of line flap- valves ; • the ARVB range for ISO PN10 type flanged flap....

ADAPTER PLATES FLAP VALVES / MULTI-MANHOLES ADAPTER PLATES A TECHNICAL DATA The ARVB range is designed for all NORHAM MULTI NB flap-valves and all other ISO PN10 flange parts. B The flap-valve is mounted on the flange using AISI316 stainless steel anchors. MATERIALS •  HDPE : body. •  EPDM : flange seal. •  Stainless steel AISI316 : mechanical anchors.

ADAPTER PLATES FLAP VALVES / MULTI-MANHOLES ADAPTER PLATES TAILOR-MADE RANGE TECHNICAL DATA Thanks to the realization of a "tailor-made" ADAPTATION FLANGE, any flat part can be mounted in a circular manhole. The mounting of the workpiece on the flange is done with stainless steel screws AISI316. The ADAPTATION FLANGE is then made of HDPE or polyester reinforced with fiberglass according to the specificity of the request.
