E2 Valve with PE tails DN 50-200

Product Description:

  • Soft seated gate valve with PE fusion tails for connection with PE pipes in compliance with EN 1555-2, DIN 8074
  • Two factory assembled PE fusion tails with screw connection to the valve body. Two independent seals and an integrated support liner assure tight connection and no gas leakage. The Hawle E2 valve with PE fusion tails is connected to the pipeline either by means of butt fusion or using electrofusion sockets.
  • One extension spindle for multiple dimensions
  • Sealing system: the wedge rubber profiles close with minimal friction in the body. There is no erasure and thus no wear of the sealing body
  • The special wedge guide in wear-resistant plastic ensures lowest wear and tear and minimum operation forces, suitable for frequent actuation at differential pressures of up to 16 bar
  • Oversized spindle nut with threads, withstands enormous operating torque
  • 100% suitable for underground installation
  • Standard model: without handwheel and extension spindle
  • Temperature range: operation: -10°C to 50°C Storage: -25°C to 70°C
