Features

N/A

  • Housing design reduces stress concentrations and prevents fatigue failure.
  • SAE-threaded or SAE DN flange porting (sizes 110-1300) to allow easy installation with maximum flexibility.
  • O-Ring seals are used to provide positive, reliable sealing. Choice of O-Ring materials (nitrile rubber, fluorocarbon elastomer, and ethylene propylene rubber) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water based fluids.
  • Removable lid requires minimal clearance to remove the element for replacement and contaminated fluid cannot be washed downstream when element is serviced.
  • HYDAC Differential Pressure Indicators have no external dynamic seal. This results in a high system reliability due to magnetic actuation, thus eliminating a potential leak point.
  • A bypass valve located in the element provides positive sealing during normal operation and fast opening during cold starts and flow surges. (Optional non-bypass available)
  • For special finishes and coatings - consult HYDAC for minimum quantities, availability and pricing.
  • Fatigue pressure ratings equal maximum allowable working pressure rating.
