TECHNICAL DATA SHEET

PRODUCT: Bellows Seal Globe Valve
MODEL / REFERENCE: DN80-PN16-RF F304
TYPE: Bolted Bonnet, Outside Screw & Yoke (OS&Y), Bellows Sealed

1.0 PRODUCT DESCRIPTION & APPLICATION
This bellows seal globe valve is engineered to provide bubble-tight shutoff and eliminate external leakage (fugitive emissions) in applications involving hazardous, volatile, toxic, or valuable fluids. The hermetically sealed metallic bellows acts as the primary stem seal, offering superior reliability over traditional packing. Constructed from ASTM F304 stainless steel, it is suitable for moderate corrosive services such as steam, hot water, general chemical processes, and other industrial applications where corrosion resistance and emission control are required.

  • Shell Test: Per API 598 standard at 1.5 x PN pressure.
  • Zkouška těsnosti sedla: Per API 598, Class IV or as specified.
  • Bellows Integrity Test: Helium mass spectrometer test or equivalent.
  • Documentation: Certificate of Conformance (COC). Material Test Certificates (MTC 3.1) available upon request.

8.0 SURFACE FINISH

  • Internal: Smooth machined finish.
  • External: Bead blasted or cleaned.
  • Paint: Exterior carbon steel components painted with anti-corrosive epoxy paint. Standard color: Blue or as per customer requirement.

9.0 OPTIONS & ACCESSORIES

  • Ovládání: Pneumatic diaphragm/cylinder, electric motor actuator.
  • Gear Operator (Recommended for DN80 manual operation)
  • Limit Switches (for actuated valves)
  • Positioners & Solenoid Valves
  • Extended Bonnet for insulation or high-temperature service
  • Different Seat/Disc Materials (e.g., hard-faced)
  • Locking Device

10.0 NOTES

  • F304 material offers good general corrosion resistance but is not recommended for severe chloride or acidic environments where F316/L would be required.
  • The bellows is a critical component. Avoid excessive stem travel and ensure proper installation to prevent damage.
  • All specifications are subject to change and must be confirmed with the final purchase order.
