Self-Actuated Valves, Pneumatic & Hydraulic Actuators
Pneumatic actuators as illustrated in Figure, provide for automatic or semiautomatic valve operation. These actuators translate an air signal into
hydraulic actuators
Working Principle of Hydraulic Actuators
Hydraulic actuators use liquid pressure rather than instrument air pressure to apply force on the diaphragm to move the valve
