  1. Gear Operator & Position Indicator Details
  • Typ: Fully enclosed worm gear unit
  • Ratio: Typically 20:1 to 40:1 (depending on size)
  • Input Torque: Designed for comfortable manual operation
  • Indicator: 0–90° movement flag type; clearly marked “OPEN” / “SHUT” or with local visual disc/flag
  • Housing: Coated cast iron or aluminium, weatherproof
  1. Testování
  • 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.
  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.
  2. Cast Iron Limitations: Avoid thermal shock or rapid temperature changes; not suitable for flammable or toxic fluids without specific approval.
  3. Gearbox: Standard with handwheel; optional chain wheel or electric actuator available.
  4. Position Indicator: Provided as standard with gear operator; if handwheel only, indicator may be optional.
  5. Flange Standard: Confirm whether BS 4504 (metric) or BS 10 (inch-based) is required.
  1. Ordering Information
