The Johnson Controls VG7842NT+423GGA is a sophisticated three-way mixing control valve made of bronze. It is constructed with a robust cast bronze body and weighs 8.4 lbs. Designed for versatile applications, it operates with a voltage rating of 24 VAC/VDC. The valve can manage temperatures ranging from 2 °C to 65 °C, making it suitable for various fluid control situations.
Engineered with a Cv rating of 11.6, this control valve is capable of delivering efficient flow characteristics, ideal for mixing operations. It has an inlet size of 1 inch (DN25), ensuring compatibility with standard piping systems through its NPT threaded end connections.
The valve is paired with the VA-4233-GGA-2 actuator, which provides a substantial force output of at least 61 lbs. It is designed to handle a maximum closeoff pressure of 208 psig (1433 kPa), allowing it to perform reliably under pressure. When handling fluids, the VG7842NT+423GGA is rated for water temperatures between 2 and 121 °C, and it can handle saturated steam at 15 psig.
A notable feature of this actuator is its hand crank manual override, which allows for immediate control in case of a power failure. Additionally, it supports AUTO stroke calibration to enhance efficiency. The flow characteristic is linear, which is essential for precise fluid mixing control, making the VG7842NT+423GGA a sturdy and reliable component in various automotive and industrial applications.
