VG7241RT+3008D Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7241RT+3008D is a 1-1/2 inch 2-way normally open globe valve assembly equipped with a pneumatic actuator featuring a 4 to 8 psi spring range. Designed for precise modulating control in commercial HVAC systems, this assembly combines a high-quality cast bronze body with brass trim to regulate the flow of hot water, chilled water, glycol solutions, and steam.

Features

• High-quality cast bronze body with brass trim for reliable performance and corrosion resistance.
• Two-way normally open configuration ensures a fail-safe open position during a loss of pneumatic pressure.
• Equal percentage flow characteristics provide precise, stable environmental control.
• Push-down-to-close stem action ensures a predictable and reliable valve response.
• Exposed yoke pneumatic actuator with a field-proven design for long-term operational longevity.
