Description
The Sporlan Controls 149074 is a 2-Way Normally Open modulating valve assembly engineered for precise flow control in commercial and industrial HVAC hydronic systems. Featuring a bronze body with stainless steel trim for superior corrosion resistance and long service life, this valve is paired with a spring return modulating actuator that ensures fail-safe operation — returning to the normally open position upon loss of power.
Key Features
- 2-Way Normally Open (NO) valve configuration for fail-safe flow control
- 1-1/4″ NPT connections for straightforward pipe integration
- 16 Cv flow coefficient with linear flow characteristic for accurate, proportional control
- Accepts 0–10 Vdc and 4–20 mA control signals for compatibility with a wide range of BAS and DDC controllers
- 24 Vac actuator power supply — standard in commercial HVAC control systems
- Spring return actuator provides reliable fail-safe operation on power loss
- Bronze body construction offers excellent durability and corrosion resistance
- Stainless steel trim for extended service life in demanding hydronic applications
- Modulating control enables precise regulation of heating and cooling media flow
