The VG7842LT+71CHGA represents Johnson Controls’ commitment to quality in the VG7000 Series of products. This three-way mixing control valve features a sturdy construction crafted from cast bronze that ensures longevity and performance in various applications. At 3/4 inches in size (DN20), it is suitable for efficient fluid control in multiple systems.
A significant characteristic of this valve is its Cv factor, which measures 7.3 Cv (6.3 Kv), providing a substantial flow rate suitable for different demands. It includes NPT threaded end connections that facilitate easy and secure installation into existing piping systems.
Designed for precise operation, the VG7842LT+71CHGA employs a proportional control mechanism with the VA7810-HGA-2 actuator, which operates at a voltage rating of 24 VAC. This actuator generates a minimum stem force output of 180 lbs, ensuring effective and responsive valve manipulation.
The unit also meets an IP54 rating, reflecting its ability to withstand dust and water splashes. It operates efficiently within a temperature range for fluids of 2 to 140 °C and maintains valve performance at operational temperatures up to 65 °C. With a rangeability greater than 100:1, it allows for precise control under varying flow conditions while featuring a leakage rating of only 0.01% of maximum flow, thereby ensuring minimal fluid loss during operation.
