for cast iron pipes and pipes with VRS-socket, Standards• Resilient seated gate valve according to EN 1171, EN 1074-1 and EN 1074-2 with smooth, straight-through boreConstruction featuresResilient seated gate valve with one-sided VRS-socket and one-sided VRS-spigot• With VRS grip ring and VRS pipe restraint clamp (not included), a pipe connection can be made restraintHawle 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 • 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 • Suitable for operation by automatic actuators • 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 600)
