Ultra High Vacuum motor Driven Gate Valves
Features:
1. Two sealing options: bellow sealing and viton sealing.
2. The valve body is welded inside stainless steel with low leakage rate
3. The valve body adopts a rib structure, small size, light weight and excellent appearance.
4. Adopt double-guide-rail structure, smooth movement, monolithic construction inside the valve and well-distributed holding power.
