  1. Функции
  • Handwheel Operation: Simple and direct manual control; suitable for most general applications.
  • Rising Stem (OS&Y): The stem rises as the valve opens, providing clear visual indication of the valve position (open or closed) without the need for an additional indicator.
  • Bronze Seated: Superior corrosion resistance and long service life in demanding fluids.
  • Metal-to-Metal Sealing: Suitable for high-temperature fluids and where rubber seals are not compatible.
  • In-Line Repairable: Packing can be replaced under pressure when the valve is fully open.

  1. Handwheel Operation Details
  • Тип: Solid or fabricated malleable/ductile iron handwheel
  • Finish: Painted (same as valve body) or epoxy coated
  • Operation Torque: Designed for comfortable manual operation by a single person (for sizes up to DN300). For DN350 and above, consult factory regarding operating effort.
  • Direction to Close: Typically clockwise (standard) – confirm with manufacturer if required.
  1. Тестирование
  • Shell Test: 1.5 x PN (24 bar for PN16) for duration per EN 12266-1
  • Seat Test: 1.1 x PN (17.6 bar for PN16) with allowable leakage per Rate D (or tighter if specified)
  • Optional: High-pressure seat test, low-pressure air test, or zero-leakage resilient seat tests available on request (not applicable to metal-seated valves).
  1. Notes & Selection Tips
  1. Bronze Seated: Ensure the application does not require zero-leakage bubble tight shut-off; metal seated valves have allowable leakage per ISO 5208.
  2. Cast Iron Limitations: Avoid thermal shock or rapid temperature changes; not suitable for flammable or toxic fluids without specific approval.
  3. Visual Indication: The rising stem provides direct visual indication of valve position. No separate indicator is fitted.
  4. Operation Torque: For larger sizes (above DN300), consider whether a gear operator is required for ease of use (handwheel only may require high operating torque).
  5. Flange Standard: Confirm whether BS 4504 (metric) or BS 10 (inch-based) is required.
  1. Ordering Information

  • Размер (DN)
  • Номинальное давление (PN)
  • Flange Standard (e.g., BS 4504 PN16)
  • End Use / Medium
  • Any special test requirements
