Overground hydrant breakable DN80 double closing with ball

APPLICATION

Waterworks and fire-fighting installations.

DESIGN FEATURES

• head, base – ductile iron EN GJS-500-7
• column:
  – 613A- carbon steel S235JR
  – 613B – stainless steel (0H18N9 / AISI 304 / 1.4301)
  – 613C – ductile iron (EN GJS-500-7 / 5.3200 / EN JS1030)
  – 613D – carbon steel S235JR hot dip galv.
• rolled stem made of stainless steel (2H13, AISI 420, 1.4021)
• protection against breaking
• stem seal – o-ring
• self – draining when fully closed
• rod:
  – column A, C, D – constructional steel with anti-corrosive coathing or stainless steel
  – column B – stainless steel
• special A2 bolt at the breaking point
• double closing system
• closing pistons – ductile iron, fully vulcanised with EPDM
• internal elements may be replaced without the need to dig the hydrant out under pressure (with the gate valve fully open)
• rotating flange – for easier installation rotates 0° to 360°
• corrosion protection:
  – external- polyester RAL3000, min. 250 μm, UV resistant
  – internal – epoxy coating approved for contact with drinking water
• optionally – brass bushing at piston working location
