MP823D001 Johnson Controls Actuator

Overview

The Johnson Controls VG7241ST+823D00 is a heavy-duty 2-inch actuated globe valve assembly designed to regulate the flow of water and steam in commercial HVAC control systems. This assembly features a 2-way normally open control valve with a cast bronze body and brass trim, paired with a spring-return pneumatic actuator operating within a 4 to 8 psi spring range.

Features

• Heavy-duty cast bronze body with brass trim provides exceptional corrosion resistance.
• Two-way normally open configuration ensures fail-safe operation to allow full flow upon loss of air pressure.
• High flow capacity with a 46.2 Cv rating and an equal percentage flow characteristic for precise modulation.
• Equipped with a standard threaded stem design for push-down-to-close action.
