The Johnson Controls VG7842ST+823E01 is engineered as a three-way mixing valve within the VG7000 Series. This unit has a rated size of 2 inches and a total weight of 26.0 lbs. The valve's body is constructed from cast bronze, while the trim is made of brass, contributing to its durability and performance. It meets ANSI B16.15 standards, classified under Class 250 for robust applications.
End connections on the valve utilize threaded (NPT) fittings. The spring range is specified to be between 9 to 13 psig. At a maximum closeoff pressure capacity, it operates effectively up to 50 psig (345 kPa). The valve fluid operating temperature spans from a minimum of 2°C up to a maximum of 140°C (35°F to 284°F), also rated for saturated steam operations at 38 psig (262 kPa).
For actuator requirements, the maximum supply pressure allowed is 25 psig (172 kPa). With a leakage classification of just 0.01% of maximum flow, this valve ensures minimal fluid loss during operation. Furthermore, it boasts an impressive rangeability exceeding 100:1, coupled with a linear flow characteristic that enhances control precision in system applications.
