ICV851/00 851/20 Air valve apex dual function

851 Air relief valve for neutral liquids AVK double orifice, triple acting air valves are designed for automatic rapid pipe filling and pipe draining as well as for automatic discharge of accumulated air during normal working conditions. The unique ‘Aerokinetic’ design, where air rushing out of the system cannot force the float upwards and close it prematurely, makes sure that the valve closes only after all air has left the system and water has entered the chamber. All ductile iron components are coated with GSK approved fusion bonded epoxy to ensure high durability. All other components are made by either a WRAS approved polymer material or stainless steel to minimize corrosion risk. All seals are made of WRAS approved EPDM rubber featuring an excellent compression set and ability to regain its original shape.
