A. Introduction

Introduction

This series of valves are made up of manual and pneumatic gate 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. 

 

Characteristics

Shaft seal is sealed by bellows, and other sealing parts are by viton, no lube;

Valve bodies material is SS structure, with small volumes and good quality;

Double-guide-rail bearing roller structure, smooth movement;

Integrated construction inside the valve and well-distributed holding power.
