Check Valves - Pressure-seal

Size 3" to 42" (80 mm to 1050 mm)
ASME Class Class 600 to 4100
Design Standard ASME B 16.34

Beyond Standards

  1. Pressure-seal Check Valve conforms to ASME B 16.34.
  2. CE Marking – Meets requirements of Pressure Equipment Directive 2014/68/EU, Annexure III, Module H
  3. Atex – Meets requirements of Atex Directive 94/9/EC (ATEX), category 2 non-electrical equipment
  4. Safety Integrity Level for Automated Valves – SIL 3 certification available

Features that Add Value:

  1. Valves in intermediate reduce cost of ownership
  2. Pressure-Seal mechanism utilizes line pressure to enhance seal; ensures sealing integrity at higher operating pressures.
  3. Higher hardfacing thickness (3 mm) to ensure consistent hot hardness
  4. Customised deposition process in F91/ C12A valves to avoid delamination of hardfaced surfaces
  5. Live loading of bonnet bolts for F91/ C12A valves
