Johnson Controls VG1245AG Valve
The Johnson Controls VG1245AG is a high-performance 1/2 inch NPT ball valve engineered for precise control in demanding HVACR systems. Featuring a 4.7 Cv rating, this two-way ball valve utilizes an Amodel flow characterization disk to provide an equal percentage flow characteristic, ensuring linear heat transfer and stable temperature regulation. Built with a forged brass body and 300 series stainless steel trim, it is rated for a static pressure of 580 psig and a close-off pressure of 200 psi. This rugged construction allows for reliable operation with hot water, chilled water, 50% glycol solutions, and 15 psi saturated steam. The VG1000 series design includes dual EPDM stem seals and 15% graphite-filled PTFE seats, tested to withstand 200,000 cycles even in iron-oxide contaminated water. Its compact footprint facilitates installation in tight mechanical spaces, making it a preferred choice for contractors looking for maintenance-free reliability and accurate flow control in automated building systems.
Key Benefits:- Optimized Flow Control: The equal percentage flow disk matches the heat exchanger's output for superior loop stability.
- Durability: Stainless steel ball and stem offer enhanced corrosion resistance and higher temperature thresholds compared to brass trim.
- Leak-Free Reliability: Double EPDM O-ring stem seals and reinforced PTFE seats ensure long-term performance under high static pressure.
- Actuator Compatibility: Designed for easy field or factory mounting with Johnson Controls VA9104, VA9203, and VA9300 series electric actuators.
- Reduced Installation Costs: Standard NPT threaded connections and a compact body design eliminate the need for extra pipe reducers or specialized tools.
- Can this valve be used for steam applications? Yes, because it features stainless steel trim, it is rated for low-pressure saturated steam up to 15 psi.
- What is the maximum fluid temperature for the VG1245AG? This model supports a wide fluid temperature range from -22?F to 284?F (-30?C to 140?C).
- Does the VG1245AG include an actuator? No, this is a "less actuator" configuration, allowing you to select the specific non-spring or spring-return actuator required for your control logic.
- Is maintenance required for the stem seals? No, the VG1000 series features a maintenance-free design that does not require packing adjustments or rebuilding.
