Stainless Steel Investment Lost Wax Casting Valve Body for Knife Gate Valve
Description
This series of valves are made up of manual, pneumatic and motor-driven gate straight valves, with reasonable design on structure and appearance is very excellent. Besides, they are with many advantages, such as stability, small size, durability, great sealing, long service life and so on, widely used in the ultra-high vacuum equipment.
Features
1. Valve bodies material is stainless steel, interior welded structure, leak rate is very lower;
2. Reinforced structure, small volume, light weight and good appearance;
3. Double-guide-rail bearing roller structure, smooth movement;
4. Integrated construction inside the valve and well-distributed holding power.
