JOHNSON CONTROLS VA9104-GGA-3S Electric Ball Valve Actuator, Proportional, 24V Voltage, Non-Spring Return

Johnson Controls VA9104-GGA-3S electric non-spring valve actuator is used in HVAC and automation systems. It is ideal for precisely controlling the valve operation and regulating the air, water or fluid flow within heating, cooling and ventilation systems. This actuator offers a seamless integration solution with remote monitoring capabilities, enhancing comfort, optimising energy efficiency and streamlining overall operation.

Johnson Controls VA9104-GGA-3S electric non-spring valve actuator is ideal for accurate positioning on ball valves in air conditioning, heating and ventilation applications.

• An electrical, pneumatic or hydraulic signal is received, indicating the desired position or movement of the valve.
• The input signal is then processed by a controller, which interprets the required valve position, amplifies it and determines the appropriate action.
• The amplified signal is then converted into mechanical energy using an electric motor or pneumatic / hydraulic pressure, depending on the type of actuator.
• The mechanical energy is transferred to the actuator's output shaft, causing it to rotate or move linearly.
• The actuator's output shaft is then connected to the valve stem or actuator mount.
• As the actuator moves, it imparts force to the valve stem, causing the valve to open, close or assume a specific position.
• The controller then continuously compares the valve's actual position to the desired position, adjusting the actuator's output signal if necessary.
• The controller ensures that the valve reaches and maintains the desired position accurately, avoiding overshooting or undershooting.
• When the valve reaches the desired position or completes its operation, the actuator stops moving and maintains the valve's position until a new input signal is received.

• Johnson Controls VA9104-GGA-3S actuator has a NEMA 2 rated enclosure for safeguarding against light splashing water and dripping.
• It features a synchronous drive for constant rotation time independent of the connected load.
• This valve actuator has a durability of up to 100000 cycles and is rated at 35 dBA for minimum noise, meeting audible noise requirements.
• It has a single screw style direct mounting design for reduced installation and maintenance time.
• This VA9104-GGA-3S actuator offers a manual override for easy manual positioning of the ball valve.
• It is equipped with a flexible metal conduit connector, simplifying field wiring and installation.
• This valve actuator can be operated at temperatures ranging from -4 to 140 degrees F.
• It is integrated with a factory-mounted valve linkage, offering streamlined and accurate valve control for optimal system performance.

• Johnson Controls M9000-561 Thermal Barrier: This thermal spacer is used with VA9104-GGA-3S actuator to enable the inclusion of low-pressure steam in the application.

• Johnson Controls VA9104-GGA-3S electric non spring valve actuator is manufactured in compliance with CE and UL standards.

Johnson Controls VA9104-GGA-3S electric non spring valve actuator is positioned & fixed onto the ball valve mounting flange, and the actuator handle is keyed onto the actuator. If the requirement is to mount the thermal barrier on the actuator, mount it before installing the ball valve. The drive shaft that connects the actuator to the ball valve is connected via a drive shaft. The drive shaft connects the ball valve to the actuator through the thermal barrier assembly. The ball valve is connected to system piping for completing the installation process. This valve features direct mount design that allows easy installation on top of the ball valve without complications. Johnson Controls VA9104-GGA-3S electric non spring valve actuator has a screw terminal style electrical connection for easily wiring the actuator.
