Pneumatic Actuator, Spring Range: 5-10 PSI, Two-Way Swivel Connection, Telescoping Linkage, for HVAC and Industrial Applications.
Overview
Details for D-4073-6002
DAMPER ACTUATOR; 5-10#SPRING BODY ONLY REPAIR
Description
The D-4073 Pneumatic Actuator is a multipurpose positioning device used to accurately position small dampers primarily on unit ventilators, VAVs, terminal units, and small ventilating dampers in response to output signals of a pneumatic controller or electro-pneumatic transducer.
The actuator is also recommended for use on other airflow control dampers, in interior locations, up to a maximum area of 6.75 sq. ft for proportional volume control and 11.7 sq. ft for two-position actuation, provided that the torque requirements are compatible with the specific application.
The D-4073 is a direct replacement for existing D-3073 actuators and a functional replacement for former D-251 actuators.
Features
- • two-way swivel connection ensures non-binding movement and full power delivery
- • glass-reinforced polymer housing, which is lightweight and corrosion- and chemical-resistant
- • telescoping linkage for fast and flexible installation
Applications
When an 8 to 13 psig spring range is used with proportional control, the damper size is limited to 6.75 sq. ft maximum. As a two-position control, damper size is limited to 11.7 sq. ft.
Three nominal spring ranges are available: 3 to 7 psi, 5 to 10 psi, and 8 to 13 psi. The control air pressure for normal HVAC operation is 0 to 20 psig.
The D-4073 incorporates several internal and external features that add functional flexibility. A two-way swivel connection on the actuator cylinder head provides non-binding movement. All actuators have a telescoping piston rod for easy linkage of the damper for attachment points up to 8-3/4 in. (222 mm) away from the face of the actuator. A swivel ball joint and slotted crankarm connector are furnished on all actuators for optional methods of linkage to the damper.
A stop screw kit is available for special applications to limit the power stroke of the actuator when required. A 4 ft (122 cm) linkage rod is also available for special applications to reach extended linkage when required.
