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 smooth, straight-through bore
Not suitable for drinking water
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
