Other Information

  • Sealing - Valves will seal against 15 psi differential atmospheric pressure in either direction.
  • Orientation - Valves can be installed in either a vertical or horizontal orientation.
  • Leak Tightness - Each valve is tested using a helium mass spectrometer leak detector calibrated for a minimum sensitivity of 2x10-10 Std. cc/sec of He
  • Maintenance - Carriage and gate mechanism may be removed through the bonnet flange for seal replacement, cleaning or retrofitting without removing the valve body from the system.
  • Manual Actuation - Actuators are constructed with non-rising Acme threads for smooth and quick operation.  Visual open position indicators are standard on all manual valves.
