Johnson Controls VG1845ER Valve

The Johnson Controls VG1845ER is a precision-engineered 3-way ball valve designed for high-performance HVACR control. Featuring a 1-1/2 inch NPT threaded connection and a robust 29.2 Cv rating, this valve utilizes a forged brass body paired with stainless steel trim to ensure long-term durability in demanding hydronic and steam environments. The integrated Amodel flow characterization disk provides an equal percentage flow characteristic, allowing for superior temperature regulation and stability compared to standard ball valves. Engineered for versatility, the VG1845ER is compatible with hot water, chilled water, 50% glycol solutions, and 15 psig saturated steam. The blowout-proof stem and dual EPDM stem seals are rated for 200,000 cycles, offering significant reliability for automated commercial HVAC service. This VG1000 series valve is frequently paired with Johnson Controls electric actuators like the VA9104 or VA9203 for seamless integration into building automation systems.

• Precise Control: The equal percentage flow disk matches the heat transfer curve of coils for stable temperature management.
• High Durability: Stainless steel ball and stem trim prevent corrosion and scaling in aggressive fluid media.
• Extended Service Life: Dual EPDM O-ring stem seals and graphite-reinforced PTFE seats are designed for over 200,000 leak-free cycles.
• High Pressure Performance: Rated for a 580 psig static pressure and a 200 psid close-off pressure for reliable shutoff.
