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 Sliding disks and ball bearing assure low friction performance of the spindle 100% suitable for buried installations Suitable for cleaning with a cleaning pig One extension spindle for several dimensions Easy refitting for position indicator and automatic actuators on the standard bonnet (DN 50 to DN 200) To set-up an actuator or a position indicator, remove the centering flange and insert position indicator or actuator with adapter (DN 250 bis DN 400) This resilient seated valve has PE tails screwed and sealed into the sockets High performance sealing of the PE tails within the sockets is assured by two separate seals and a support liner The valve can be connected to the PE pipeline by either butt fusion or electrofusion Standards Resilient seated gate valve according to EN 1171, EN 1074-1 and EN 1074-2 with smooth, straight-through bore
