          High vacuum gate valve

          Product description
          ULTRA-HIGH VACUUM GATE VALVES
          BRIEF INTRODUCTION 
          This series of valves are made up of manual, pneumatic and electromagnetic gate straight valves. The design of this series’ structure is reasonable, and the appearance is excellent. Besides, they have many advantages, such as stability, small size, durability, great sealing, long service life and so on. As a result, they can apply to the ultra-high vacuum equipment.
          FEATURES 
          1. Adopt stainless steel bellows and viton o- ring sealing, no lube.
          2. The inner of valves’ body is welded by stainless steel and leak rate is low.
          3. Valve body design in rib structure, with small sizes, excellent appearance and light quality.
          4. Adopt double-guide-rail structure, smooth movement; monolithic construction inside the valve and well-distributed holding power.
