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. Atm. cc/sec of He. Internal welds are inspected for pits, cracks, and
other irregularities which may cause virtual leaks.
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.
