2-Port Shutoff Valves and 3-Port Changeover Ball Valves, PN 40, with Internally Threaded Connection VAI60

Description: The 2-Port Shutoff Valves and 3-Port Changeover Ball Valves, PN 40, with Internally Threaded Connection VAI60 are designed for use in heating, ventilation, and air conditioning (HVAC) plants as shutoff or changeover ball valves within closed circuits. Offering versatility and reliability, these valves are engineered to meet the demands of diverse HVAC applications.

Key Specifications:

  • Valve Body: Constructed of brass, UNS C35330 (DZR), ensuring durability and resistance to corrosion.
  • Size Range: Available in sizes DN 15 to DN 50, catering to various system requirements.
  • Flow Capacity (kvs): Ranges from 5 to 96 m³/h, providing flexibility in fluid handling capabilities.
  • Connection Type: Internally threaded connections (Rp) per ISO 7-1, facilitating secure and leak-proof installations.
  • Rotational Angle: 90° rotation for easy operation and control.
  • Compatibility: Compatible with electromotorized rotary actuators GQD..9A, GMA..9E with spring return, and GSD..9A, GDB..9E, GLB..9E without spring return, offering versatile control options.
  • Auxiliary Functions: Suitable for applications with auxiliary functions such as auxiliary switches, potentiometers, and standard rotary actuators from the DAC product range.

Key Features:

  • Moderate Price: Optimized flow rates enable the selection of smaller ball valves, reducing costs. Low torque requirements allow for the use of smaller, less expensive rotary actuators.
  • Long Life Expectancy: Maintenance-free design with low friction stem and a polished ball made of chrome-plated DZR brass ensure longevity and reliable performance.
  • Simple Mounting: Pre-mounted brackets on the actuators facilitate tool-free mounting on the ball valves, streamlining installation processes.

The 2-Port Shutoff Valves and 3-Port Changeover Ball Valves, PN 40, with Internally Threaded Connection VAI60 offer efficient fluid control solutions for HVAC systems, combining durability, performance, and ease of installation at a competitive price point.
