The VG7842NT+3008DP model by Johnson Controls serves as a three-way mixing control valve built from durable cast bronze. With a weight of 8.5 lbs, this valve is structured to handle flow dynamics effectively within a temperature spectrum of 2 °C to 65 °C.
It incorporates a brass bonnet and linear trim, which promotes optimal performance across various applications. The valve measures 1 in. (DN25) in size and has an impressive Cv rating of 11.6, indicating its capacity for efficient fluid passage. NPT threaded end connections facilitate straightforward integration into different setups.
The actuator associated with this valve is the V-3000-8012 model, designed for effortless operation with an effective area of 8 square inches, constant throughout the entire stroke. This actuator supports a maximum closeoff pressure of up to 76 psig (524 kPa). Additionally, the fluid temperature it can manage spans from 2 to 140 °C for water and accommodates saturated steam at 38 psig.
With a maximum actuator supply pressure rated at 25 psig (172 kPa), the VG7842NT+3008DP consistently meets appropriate operational standards. Its flow characteristic is classified as linear, ensuring straightforward control of flow rates within the system under varied conditions.
