Manual and Pneumatic Gate Valves The 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. The valves are available with flange options of ISO, CF (metal sealed) for applications at ultra high vacuum requiring increased bake-out temperatures. The stainless steel valve bodies are vacuum brazed, a special process which includes a bake-out 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. In situ 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. Manual or pneumatic options. Microswitch position indicator as standard on pneumatic version suitable for magnetic fields. Long periods of use between maintenance. Low vibration and shock. Free choice of orientation. Wide range from 40 mm/1.56 inch bore up to 320 mm/12.48 inch bore. Flange options – ISO, CF (metal sealed) Vacuum brazed to 1100 ˚C to eliminate virtual leaks.
