Equalizing/Relief Valves

Design Features Of Equalizing/Relief Valves

  • Fabricated Construction
  • Valve actuation with hydraulic Cylinder (Standard)
  • Pressure rating up to 3,0 bar
  • Service temperatures up to 500 °C
  • Nominal sizes DN 250 – DN 600
  • Other sizes or operating conditions on request
  • The forged arm has been replaced by a shaft and a lever
  • The lever/ flap assembly may be dismantled as one unit
  • The seat is a separate part in order to make replacement easier
  • Being located inside the casing, the seat may be replaced without removing the valve casing

This Design Guarantees

  • Seat may be dismantled through the maintenance door without removing the valve itself
  • Reduced maintenance and improved accessibility of equipment due to large maintenance door
  • The dismantling of the welded lever/ flap unit is possible, thus facilitating maintenance and exchange
  • Higher reliability & availability thanks to continuously improved design and customer feedback over several years
