GI/ GIQ/ GI-C series Pneumatic high vacuum butterfly valve

Butterfly Valve

Features
GI/GIQ is used to cut through or to put through the air currents of vacuum tube or to apply for air and the work of non-corrosive gases medium.
GI-C is used to regulate gas flow of the vacuum system. Working medium is applicable to non-corrosive gases and air. Connecting flange standards is JB919.
