 Upgrade your heating, ventilation, and air conditioning systems with Siemens' VAI61 Series Ball Valves. These 2-way internal thread ball valves are engineered to provide reliable and efficient control for closed circuits, making them an invaluable addition to your HVAC setup. Let's explore the key features that set these ball valves apart.

Key Features:

  • Robust Construction: The ball valve body is crafted from high-quality brass (UNS C35330 DZR), ensuring durability and longevity.

  • Versatile Sizing: Available in various sizes, ranging from DN 15 to DN 50, to accommodate your specific requirements.

  • Optimized Flow Rates: The ball valves are designed to offer excellent flow rates, allowing you to choose smaller, cost-effective valves without compromising performance.

  • Internal Threading: Featuring internal threads per ISO 7-1, making installation and connection a breeze.

  • Precise Control: With a 90° rotational angle, you can achieve precise control over your HVAC system.

  • Compatible with Actuators: These ball valves can be seamlessly integrated with Siemens' electromotorized rotary actuators, including modbus variants, ensuring efficient and automated control.

  • Optional Auxiliary Functions: For applications with auxiliary functions, such as auxiliary switches or potentiometers, these ball valves can be combined with standard rotary actuators.

Exceptional Performance:

The Siemens VAI61 Series Ball Valves are designed to provide high-performance control with cost-efficiency in mind. Thanks to their optimized flow rates, you can select smaller ball valves, reducing costs while maintaining functionality. The construction of the valves is virtually maintenance-free, featuring a low-friction stem and a polished ball made of chrome-plated DZR brass.

Effortless Installation:

Installing these ball valves is a hassle-free process. The brackets, which come pre-mounted on the actuators, allow for tool-free mounting on the valves, saving you time and effort during setup.

Upgrade your HVAC system with Siemens VAI61 Series Ball Valves for precise, efficient, and cost-effective control. These ball valves offer durability, simplicity, and optimal performance, making them an excellent choice for your heating, ventilation, and air conditioning applications. Ensure the smooth operation of your HVAC system by integrating Siemens' reliable and high-quality ball valves.
