Description
The Reznor 258318 is a two-way, normally open valve assembly engineered for reliable flow control in commercial HVAC hydronic and heating applications. Combining a high-flow brass ball valve body with a direct-coupled, spring-return actuator, this assembly delivers precise two-position control with minimal pressure drop and long service life.
Valve Features
- Two-way, normally open (N.O.) configuration
- 3/4″ NPT end connections for straightforward pipe installation
- 29 Cv flow coefficient for high-capacity flow performance
- Equal percentage flow characteristic for accurate modulation
- Brass body construction with plated brass trim for corrosion resistance and durability
Actuator Features
- 24VAC power supply — compatible with standard HVAC control systems
- Spring-return mechanism ensures fail-safe normally open position on power loss
- Two-position (on/off) SPST control signal
- Direct-coupled design eliminates linkages for reliable, maintenance-friendly operation
Applications
- Commercial and industrial hydronic heating systems
- Unit heaters, cabinet heaters, and fan coil units
