P470FB-1C Johnson Controls Pressure Control

Overview

The Johnson Controls VG7842ES+8122G is an actuated valve assembly that combines a 1/2-inch 3-way mixing cast bronze globe valve with a VA-8122-1 non-spring-return proportional electric actuator. Designed to deliver precise modulating flow control, it features a robust cast bronze body with brass linear trim. The integrated actuator includes intelligent features like automatic calibration to streamline installation and commissioning.
