Overview of the range of butterfly valves
 |
Butterfly Valves VFA The VFA are maintenance-free intermediate flange flaps of the pressure class PN16 in the nominal diameter range DN25/32 to DN300. They are intended for use in cold and cooling water systems, heating systems, sewage, drinking water and domestic water. On request, these flaps are also available in the version with threaded eyes. The housing consists of lacquered cast iron, the washer up to DN80 of stainless steel. For larger nominal diameters, the washer is also made of cast iron. The gasket is a soft-sealing EPDM cuff seal. The butterfly valves can be used in the temperature range of -10... + 130 °C. A large number of actuators are available for adjustment of the flaps. Up to nominal diameter DN100 can JOVENTA-Flap Actuators Or the OM-1 rotary drive is used by Ari. Corresponding OM drives are also available for the larger nominal diameters. Datasheet  vfa_d  Vfa_e |
