Overview and Applications

Availability

The MVG (Manifold Valve Gate) system is ideal for all applications which require high speed, sequential filling or highly cosmetic gates. Due to its multiple gating options and lack of material traps it will operate with the most demanding materials. The MVG is designed for easy installation due to simple mounting in the backplate with integral airways.
