Ultra-High Vacuum Motor Driven Gate Valve

Short Description:

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.
