Description
The NBK Parts 20201 is a heavy-duty, 2-way normally closed solenoid valve engineered for steam and demanding fluid control applications. Built with a pilot-operated design, a robust brass body, and an explosion-proof enclosure, this valve delivers reliable shut-off performance in industrial and commercial HVAC environments where safety and durability are non-negotiable.
Key Features
- 2-way, normally closed (NC) configuration — valve closes automatically when de-energized for fail-safe operation
- Pilot-operated design for efficient, low-power actuation across the rated pressure range
- 3/4″ NPT end connections for straightforward installation into standard piping systems
- 120VAC coil voltage — compatible with common commercial and industrial control circuits
- 5 Cv flow coefficient for optimal flow capacity in steam and compatible media applications
- Rated operating pressure range: 0–50 PSI
- Brass body construction for excellent corrosion resistance and long service life
- EPDM seals — well-suited for steam service, hot water, and other high-temperature media
- Explosion-proof enclosure for safe deployment in hazardous or classified locations
