Pendulum valve control system

Product catalog summary
Overview: The document provides detailed technical specifications and operational guidelines for the VAT Series 65 pendulum valve control system, designed for downstream pressure control and isolation. It highlights the compact design, fast operation, and integrated high-performance controller.
Specifications: The valve is made from aluminum and features a low minimum controllable conductance. It is available in various sizes (DN 100 to DN 400) with different interface options including RS232, Logic, and DeviceNet®. The valve can be configured with optional features such as Sensor Power Supply (SPS) and Power Failure Option (PFO).
Technical Data: The valve operates with a power consumption of 24 V DC, with a maximum of 50 W for the controller and motor. It supports a sensor supply of 24 V DC or ±15 V DC and offers a control accuracy of 0.1% of the maximum sensor range. The ambient temperature for operation is recommended to be below 35°C.
Functionality: The valve plate acts as a throttling element, with the integrated controller calculating the required position to achieve the setpoint pressure. The Series 651 features an extended control range and minimized conductance, with a unique stroke movement for precise control.
Pressure Control: The controller ensures fast and accurate pressure control with an automatic learning function for system parameters. It supports remote control via RS232, Logic, or DeviceNet® interfaces and includes a service port for computer connection.
Maintenance: The valve is designed for easy maintenance, allowing for quick removal and reinstallation of the pendulum plate and sealing ring. Only two standard tools are required for maintenance tasks.
Options and Accessories: Various accessories are available, including connector kits, power supply units, and software packages for enhanced control and performance analysis. The valve can be customized with different actuator options, flange types, and sealing materials.
Performance Comparison: The document compares Series 650 and Series 651, noting that Series 651 offers an extended control range and reduced pressure rise time, with very low vibration levels.
