China-KF-LF-CF-Manaul-Pneumatic-Electric-Vacuum-Angle-Block-Valve

Name: Vacuum Block Valves

This series of valves are made up of manual, pneumatic and electromagnetic block straight valves. The design of this series' structure is reasonable, and the appearance is excellent. Besides, they have many advantages, such as stablity, small size, durability, great sealing, and long service life and so on.

Features:
1. Simple structure and easy to change and maintain.
2. Easy to clean up.
3. Electromagnetic valves are designed in an energy saving way and the size is small.
