Key Suppliers of VALVE ACTUATORS.

VALVE ACTUATORS, a type of VALVES.

Valve Actuators are a type of Valves. Actuators are fitted to control valves when fine positioning is required or where manual operation is impractical—such as in subsea environments—and they convert control signals into valve movement. Although subsea actuators overlap with other categories, they are described separately because they must be specially engineered to cope with very high pressures and low temperatures and thus call for dedicated expertise. The technology also differs depending on the operating environment; for instance, pneumatic actuators are seldom used underwater because the ambient pressure is too high.
