EM series non-invasive integrated switch explosion-proof type

The "EM" series features a compact structure, small size and light weight. It is mainly used to operate valves that rotate 360° for multiple turns, such as gate valves and globe valves. The combination of linear thrust units, bases, crank arms, reducers and other mechanical components controls other types of valves, such as butterfly valves, ball valves, dampers, baffle valves, plug valves, louvers, etc.
