PNEUMATIC PISTON ACTUATOR DELAN ENERGY This series is a pneumatic piston type actuator with high output and performance, used in combination with straight stroke control valves, including globe valves, cage valves, gate valves, etc. The design of this series of actuators enables reliable switching or adjustment control of the control valve. This series of actuators is divided into two types: single action and double action. The single action actuator is divided into two types: direct action (GD-Z) and negative action (GD-F), and is a spring loaded cylinder type actuator; The double action (GD-D)...

STANDARD PIPING CIRCUIT The top mounted handwheel on the GD type actuator can be used to set the travel limit in the upward direction. The handwheel of the GD-Z type actuator rotates clockwise to cause the actuator push rod to move downward and compress the spring; When the handwheel rotates counterclockwise, the action of the spring pushes the push rod back. For GD-F actuators, counterclockwise rotation will move the push rod upwards; When rotating clockwise, the action of the spring pushes the push rod back down. The side-mounted handwheel on the GD actuator is positioned on one side of the...
