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
Resilient seated gate valve with flange and PE fusion tail
- This resilient seated valve has one flange and one PE tail 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)
