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.  Atm. 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.
