The Siemens SSC319 servo drive is commonly used in heating, ventilation, and plumbing systems where precise control of flow is required. It is typically installed in commercial and industrial buildings, including large-scale HVAC systems and process control applications. Installers and technicians working with these systems will find the SSC319 suitable for applications where a 3-position control system is needed to regulate the position of the valve accurately. The drive is designed to work with a range of valve types and sizes, making it a versatile component in complex control systems.

Its integration into the system allows for automated control of valve movement, ensuring consistent and reliable operation. The drive is often used in conjunction with thermostats, controllers, and other system components to maintain desired flow rates and temperatures. The manual override feature is particularly useful during maintenance or system testing, allowing for temporary manual control without the need for electrical power.

Technical parameters

Nominal light	DN 25
Weight	5 kg
Code	SSC319
Brand	SIEMENS

The nominal light of DN25 indicates the size of the valve it is designed to operate, while the switching force of 300N ensures sufficient actuation power for the selected valve sizes. The stroke of 5.5 mm defines the range of movement the drive can provide, which is essential for accurate positioning in control applications. These parameters are critical for correct sizing and selection of the drive to match the specific valve and system requirements.Installation and connection When installing the Siemens SSC319, ensure the drive is correctly aligned with the valve stem and that all mounting brackets are securely fastened. The drive connects to the valve using the appropriate type and must be compatible with the valve model specified in the technical documentation. Verify that the electrical connections are made to a 230V AC using the correct wiring . A common mistake during installation is incorrect alignment of the drive with the valve stem, which can lead to improper operation or mechanical stress on the components. Always double-check the valve model and thread type before final installation to avoid compatibility issues.Compatibility and accessories The Siemens SSC319 is specifically designed for use with VVP459, VXP459, and VMP45 valves in sizes from DN25 to DN40. It is essential to confirm the exact valve model and size before installation to ensure compatibility. No additional accessories are required for standard installation, but it is recommended to have spare parts such as seals and fasteners on hand for maintenance purposes. No related products are listed for this model.Technical background for designers The Siemens SSC319 operates using an that converts electrical energy into mechanical movement, allowing the drive to control the position of the valve. The drive is constructed using durable materials suitable for industrial environments. Its integration into the system requires careful consideration of the control signals and power supply to ensure smooth and reliable operation. The service life and efficiency of the drive are influenced by factors such as the quality of the installation, the of use, and the maintenance schedule. Proper alignment and regular inspection are essential for maintaining performance over time.Service and operation The Siemens SSC319 requires minimal maintenance under normal operating conditions. However, it is recommended to periodically inspect the drive for signs of wear, misalignment, or mechanical stress. Check the electrical connections for any signs of damage or looseness. No specific service intervals are provided in the technical documentation, but routine checks are advised to ensure continued reliable operation. If the manual override is used frequently, it is important to ensure that the drive is returned to automatic mode after each use to prevent unintended system behavior.Frequently asked questions

Can the Siemens SSC319 be used with valves larger than DN40?
No, the drive is specifically designed for use with valves from DN25 to DN40. Using it with larger valves may result in insufficient actuation force or mechanical failure.

Is the manual override available during automatic operation?
Yes, the manual override can be engaged at any time to allow for temporary manual control of the valve position, even when the drive is operating in automatic mode.

What type of electrical supply is required for the Siemens SSC319?
The drive requires a 230V AC power supply. It is important to ensure that the electrical connections are made according to the manufacturer's specifications to avoid damage or malfunction.

Can the Siemens SSC319 be integrated with a building automation system?
Yes, the drive is compatible with standard control systems and can be integrated with building automation systems using the appropriate control signals and wiring.
