E3 gate valve for gas, PE ends | PN 6

Resilient seated gate valve with smooth, straight-through bore

• 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

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
• 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 400)

• Resilient seated gate valve according to EN 13774 (EN 1074-1 und 2) with smooth, straight-through bore
• Temperature range:
  • operation: -10° C to 50° C
  • Bearing: -25° C to 70° C

• Soft seated gate valve with PE fusion tails for Connection with PE pipes in compliance with EN 1555-2, DIN 8074
