VG7441RT Johnson Controls Valve

Overview

The Johnson Controls VG7441RT is a 2-way, normally closed (NC) globe valve engineered for precise flow control in commercial HVAC hydronic systems and steam applications. Housed in a rugged cast bronze body with brass trim, this straight-through valve utilizes a push-down-to-open (PDO) action, providing a fail-closed safety position to protect systems during an actuator power loss. Its equal percentage flow characteristic ensures accurate modulation, making it an ideal choice for variable flow distribution systems where tight environmental control is essential.

Features

• Two-way normally closed (NC) push-down-to-open (PDO) configuration
