Johnson Controls VG1245CPH923AGA Valve Assembly

Upgrade your building automation system with the Johnson Controls VG1245CPH923AGA, a high-performance 1-inch 2-way normally open ball valve designed for the most demanding HVAC and steam applications. This VG1000 Series assembly features a rugged forged brass body and 300-series stainless steel trim, specifically engineered to handle saturated steam up to 15 psi. With an 18.7 Cv rating and an Amodel flow characterizing disk, this valve ensures precise equal percentage flow control, eliminating the temperature fluctuations common in inferior setups. Its integrated thermal barrier and M9000-561 linkage protect the VA9208-AGA-2 spring return actuator from high media temperatures, ensuring reliable fail-safe operation in steam or hot water loops. This 24V control valve supports both two-position and floating point signals, offering maximum flexibility for modern plant managers looking to optimize HVAC valve assembly performance and thermal efficiency.

• Steam Rated Durability: Equipped with stainless steel trim and a specialized thermal barrier to withstand saturated steam environments up to 15 psi and fluid temperatures up to 284°F.
• Precision Modulation: The equal percentage flow characteristic provides a linear heat output, essential for stable control in AHUs and heat exchangers.
• Fail-Safe Reliability: The spring return normally open configuration ensures the valve defaults to the open position during power loss, preventing system freeze-ups or flow interruptions.
• Leak-Free Performance: Features 15% graphite-reinforced PTFE seats and EPDM O-rings, tested to exceed 200,000 cycles for maximum service life in contaminated water systems.

What is the maximum pressure rating for this assembly?
The Johnson Controls VG1245CPH923AGA is rated for a static pressure of 580 psig and a close-off pressure of 200 psi, making it suitable for high-pressure commercial hydronic systems.

Can this valve be used for chilled water applications?
Yes, while it includes a thermal barrier for steam, this valve is equally effective for chilled water and glycol solutions (up to 50%), providing a wide media temperature range of 23°F to 284°F.

Is the actuator compatible with 24VAC or 24VDC?
The integrated VA9208 series actuator is a universal 24V unit, compatible with both 24VAC and 24VDC power sources for two-position or floating control logic.
