Quality, safety, durability: these characteristics are essential for gate valves. We have therefore incorporated our many years of experience into developing our E3 gate valves to give them the finishing "Made for Generations" touch. The result: Hawle E3 gate valves are unrivalled in terms of reliability thanks to their Duplex stainless steel spindle fitted as standard, their permanent ease of operation and their 100% corrosion protection. Features The Hawle E3 spigot valve with smooth spigot ends is a universal type, suitable for both flange as well as for socket connections Easy replacement of old flange valve to insertion of HAWLE flange, as insertion of flat gaskets is not required; special lengths can even be produced through shortening of the spigot ends The outside diameters of the spigot ends correspond to that of the cast iron pipes (other size on request) Hawle E3: Double bayonet O-ring carrier is connecting the spindle to the bonnet, allowing a fully encased, uniform epoxy powder coated bonnet for further improved corrosion protection Spindel made of Duplex stainless steel Wedge guide made of wear resistant POM material in load optimized design minimizes attrition and ensures lowest torque actuation Wedge is flexible and fully linked in vulcanized elastomer to the wedge nut. This snug fit dampens vibration during opening and closing of the wedge Wedge nut has a long thread length allowing significantly higher torques than the standard before breaking O-rings, lip-seals mounted in the bonnet are replaceable under operating pressure Extended edge protection to avoid damages during transport, storage and assembly
