Johnson Controls VG1241AE Valve
The Johnson Controls VG1241AE Valve is a 1/2-inch NPT two-way ball valve engineered for precise performance in HVACR systems. Built with a forged brass body and plated brass trim, this component is designed to regulate the flow of hot water, chilled water, or 50% glycol solutions effectively. It features an Amodel flow characterization disk that provides an equal percentage flow characteristic, ensuring linear heat output and stable control across varying load conditions. With a 1.9 Cv rating, this valve effectively handles pressure drops up to 50 psid, while the graphite-reinforced PTFE seats and dual EPDM stem seals support a life expectancy of 200,000 cycles. This VG1000 Series ball valve is compatible with VA9104 or M9109 non-spring return actuators and VA9203 or VA9208 spring return actuators, making it a versatile choice for direct-coupled electric valve actuator applications in commercial mechanical rooms.
Key Benefits for HVACR Contractors- High Durability: The forged brass body is rated for a 580 psig static pressure (PN40), providing robust resistance against system surges.
- Precision Control: Characterized inserts eliminate the need for pipe reducers and prevent "hunting" in the control loop by maintaining consistent flow.
- Leak-Free Operation: Features a 15% graphite-filled PTFE ball seat and EPDM o-rings, meeting ANSI Class IV leakage standards.
- Compact Profile: The maintenance-free design is ideal for tight-fit locations where traditional globe valves cannot be serviced.
What actuators are compatible with the VG1241AE?
This valve is designed for use with Johnson Controls VA9104 and M9100 Series non-spring return actuators or VA9203 and VA9208 Series spring return actuators for on/off, floating, or proportional control.
Can this valve be used for steam applications?
The VG1241AE features brass trim and is rated for water and glycol. For low-pressure steam up to 15 psig, a stainless steel trim model from the VG1000 series should be selected instead.
How does the equal percentage flow benefit the system?
The equal percentage characteristic compensates for the non-linear heat transfer of coils, allowing the controller to maintain a much more stable temperature setpoint compared to standard quick-opening valves.
