BOC Edwards Description by Part Number:
Product Name: GVI063M Gate Vale ISO63
Product Description: GVI063M Gate Valve Manual ISO63 Flange
The BOC Edwards GV range of stainless steel, bellows sealed gate valves is designed for applications requiring overall leak tightness and a minimum of hydrocarbon in the residual atmosphere.
These superior quality valves offer high vacuum integrity coupled with maximum conductance. These GV Valves are available with ISO flanges . ISO and ANSI valves are supplied with fluoroelastomer bonnet seals. All GV Valves have fluoroelastomer valve plate seals.
* In site removal of gate and linkage mechanism for easy servicing
* Virtual leaks eliminated due to vacuum brazed manufacture
* Electropolished finish inside and outside
* Compact design with high conductance
* Long periods of use between maintenance
The stainless steel valve bodies are vacuum brazed, a special process which includes a bakeout at 1100 C. This eliminates any possibility of virtual leaks and ensures a product with low outgassing characteristics.
A laser welded stainless steel bellows effectively seals the actuator from the valve. The concept provides ease of servicing and allows the gate and linkage mechanism to be removed while the valve remains in situ.
