Siemens, 171C-10600-0.8-1.2, Non-Spring Return 1/2" 6-Way Ball Valve and Actuator Assembly, A=0.8CV, B=1.2CV, 58psi Close-Off, NPT Union Internal Thread, 0-10V NSR
Features:
- Control two media sources (hot and chilled water) to a single coil with one valve and actuator.
- Built-in pressure compensation function.
- Zero leakage - No mixing of hot and chilled water.
The 171C Series 6-way ball valves couple with the GDE161.1P OpenAir™ Actuator to provide single valve and actuator changeover and control of hot and chilled water for heated/chilled beam applications or any four-pipe system.
The 6-way ball valve, using a single actuator, shall switch (changeover) and control two media sources serving a single coil or heating/cooling beam (chilled beam). The 6-way ball valve shall have a linear flow characteristic for both media sources. The valve shall be closed to flow at mid-rotation (45°).
