Part number VG1845DR from Johnson Controls, listed in Valves & Process Control. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls VG1845DR is a high-performance 1-1/4 inch 3-way ball valve designed for precise modulating or on/off control of hot water, chilled water, and up to 50% glycol solutions in commercial HVAC systems. Part of the VG1000 Series, this valve features an equal percentage flow characteristic and is designed to integrate seamlessly with various Johnson Controls spring return and non-spring return electric actuators. It is shipped as a valve-only assembly, allowing for flexible actuator pairing depending on building automation system requirements. Features Equal Percentage Flow: Equipped with an Amodel flow characterizing disk to maintain accurate, stable temperature control. High Closeoff Pressure: Provides a tight shutoff rating of 200 psi to ensure operational reliability. Durable Construction: Engineered with a blowout-proof stem and a service life expectancy of at least 200,000 cycles. Low Leakage Rate: Meets ANSI Class IV leakage standards, restricting leakage to a maximum of 0.01% of Cv. Premium Seals: Utilizes an EPDM double O-ring stem seal and graphite-reinforced PTFE seats for a leak-free design. Specifications Valve Size: 1-1/4 inches Connection Type: Female NPT (National Pipe Thread) Tapered Body Pattern: 3-way mixing or diverting Flow Coefficient (Cv): 29.2 (Port A), 14.6 (Bypass Port B) Rangeability: 500:1 Body Material: Forged Brass Ball and Stem Material: 300 Series Stainless Steel Fluid Temperature Range: -22 to 284 degrees Fahrenheit (-30 to 140 degrees Celsius) Pressure Rating: 580 psig (PN40) Applications Commercial HVAC hydronic heating and cooling systems Air handling unit (AHU) coil control Fan coil unit (FCU) flow regulation Chilled and hot water distribution piping loop management Integration into building automation and energy management systems
