The VG7842ST+7150G is engineered as part of the VG7000 Series by Johnson Controls, serving as a reliable 3-way mixing globe control valve. Weighing 17.7 lbs, it is designed with a 2-inch size and features NPT threaded connections for easy integration into existing systems. Made primarily from cast bronze, the valve ensures durability while offering brass trim to enhance performance longevity.
The integrated actuator, identified as VA-7150-1001, functions with a non-spring return mechanism. It operates on a voltage rating of 24 VAC and delivers a force output of 90 lb, allowing it to effectively control fluid flow for various demanding applications. This valve uses a three-wire control type with an on/off (floating) function, offering precise actuation based on system demands.
Temperature capabilities for the VG7842ST+7150G range from 2°C to 65°C, permitting it to function effectively in a variety of environments. The valve can accommodate a maximum fluid temperature of 140°C for water applications and handle up to 38 psig for saturated steam scenarios. Furthermore, it has a closeoff pressure rating of 21 psig (145 kPa), ensuring it maintains effective sealing during operation.
With a body rating according to ANSI B16.15 at class 250, this valve exhibits reliable structural integrity. Leakage is minimized to 0.01% of maximum flow, in compliance with ANSI/FCI 70-2 class 4 standards, making it an ideal choice for applications where data accuracy and fluid control are critical.
