E2 Valve Flanged Ends DN 250-500

Product Description:

  • Soft wedge gate valves with clear cut and free flowing passages in compliance with EN 13774 (EN 1074-1 and 2)
  • Readily operated without a bypass or power reinforcement – even at 16 bar differential pressure 
  • Sealing system: the wedge rubber profiles close with minimal friction in the body. There is no abrasion 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 
  • Roller bearing as a spindle bearing ensure minimum operation force
  • Standard model: without handwheel and extension spindle
  • Model variants: with position indicator No. 4005STE2
  • Flanges measured and drilled to EN 1092-2. Standard PN 10. Please indicate PN 16 when ordering.
  • Temperature range: operation: -10° C to 50° C Bearing: -25° C to 70° C
