GVA AND AVA SERIES ALUMINUM GATE
AND ANGLE VALVES
BOC Edwards' new line of lightweight aluminum gate and angle valves are designed for high vacuum service and are well suited for isolation of roughing lines and forelines in a vacuum process where high conductance is required. An optional position indicator is available, which is activated by a magnet inside the pneumatic actuator providing indication for the open and closed positions. Easy removal of the actuator allows servicing while the valve body remains in situ. |
Features & benefits
• Lightweight aluminium design
• Pneumatic operation
• ASA flanges standard (optional flanges available on request)
• Flange and bore dimensions range 2" to 24"
• Optional position indicator available
• Valve closes upon loss of power and/or pneumatic pressure
• In situ removal of actuator assembly for easy servicing
• Minimal spares required for servicing
