Description
The Johnson Controls VG7241ET+7150G is a complete valve and actuator assembly engineered for precise hydronic and HVAC flow control in commercial building automation systems. Combining the VG7241ET globe valve body with the 7150G non-spring return actuator, this pre-matched assembly delivers reliable, repeatable performance right out of the box.
Valve Body — VG7241ET
- Pipe size: 1/2″ NPT
- Configuration: 2-way (two-port) flow control
- Flow characteristic: Equal percentage — ideal for stable control across a wide load range
- Flow coefficient (Cv): 1.8
- Body material: Cast bronze for superior corrosion resistance and durability
- Trim material: Brass for reliable seating and long service life
Actuator — 7150G
- Control voltage: 24 Vac
- Actuation type: Non-spring return — valve holds last position on power loss
- Control signal: Three-wire incremental (floating point) for precise modulating control
- Compatible with building automation and DDC control systems
Key Features & Benefits
- Factory-matched valve and actuator assembly for simplified installation
- Equal percentage flow characteristic provides excellent controllability at partial loads
- Cast bronze body withstands demanding hydronic system conditions
- Non-spring return actuator retains valve position during power interruptions
- Three-wire incremental control signal integrates easily with most DDC and BAS controllers
- 24 Vac operation compatible with standard low-voltage control wiring
- Compact 1/2″ NPT connection suits tight mechanical room installations
Typical Applications
- Fan coil unit heating and cooling coil control
- Air handling unit heating/cooling coils
- Terminal unit hydronic flow regulation
- Commercial building automation and DDC systems
- Chilled water and hot water distribution systems
