The Magnatrol 133GR27-G is a 2-inch normally open (N/O) solenoid valve designed for dependable, automatic flow control in demanding HVAC, hydronic, and industrial piping applications. Rated for 120V operation, this valve defaults to the open position when de-energized, making it ideal for fail-safe system designs where uninterrupted flow must be maintained during a power interruption.
Key Features
- 2″ pipe size for high-flow capacity applications
- Normally Open (N/O) operation — valve opens when de-energized for fail-safe performance
- 120V coil voltage for compatibility with standard commercial and industrial control circuits
- Robust solenoid construction engineered for long service life in continuous-duty environments
- Suitable for HVAC, hydronic heating and cooling, steam, water, and other compatible media systems
- Direct-acting or pilot-operated design provides responsive, precise flow switching
