Description
The Johnson Controls VG7241ES+3801D is a factory-assembled, 2-way normally open control valve paired with a spring-return pneumatic actuator — engineered for reliable flow control in commercial HVAC hydronic and steam systems. The cast bronze body with brass trim delivers long-lasting corrosion resistance, while the equal percentage flow characteristic provides precise, stable modulation across a wide range of load conditions.
Valve Features
- 2-way, normally open configuration
- 1/2″ NPT end connections for straightforward installation
- 1.8 Cv flow coefficient for accurate flow sizing
- Equal percentage flow characteristic for superior part-load control
- Cast bronze body with brass trim for durability and corrosion resistance
Actuator Features
- Spring-return pneumatic actuator (Model 3801D)
- 4–8 PSI spring range for precise pneumatic modulation
- Spring-return action provides fail-safe normally open position on air loss
- Designed for use with standard pneumatic control systems
Applications
- Commercial HVAC hydronic heating and cooling systems
- Air handling units and fan coil units
- Chilled water and hot water coil control
- Pneumatically controlled building automation systems
Why Choose the VG7241ES+3801D
This pre-assembled valve and actuator combination from Johnson Controls simplifies installation and ensures factory-matched performance. The equal percentage flow characteristic makes it ideal for applications requiring stable control across varying load conditions, and the spring-return actuator provides an added layer of safety by returning the valve to its normally open position upon loss of pneumatic signal.
