VG7243ET+3008BP Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7243ET+3008BP is a professional-grade pneumatic control valve assembly designed for precise fluid control in HVAC systems. It features a 1/2-inch 2-way globe valve configured as normally open, paired with a reliable pneumatic actuator using a 3 to 6 psi spring range. Constructed with a cast bronze body and high-grade stainless steel trim, this assembly ensures long-term durability and structural integrity in demanding environmental control applications.

Features

• Two-way normally open configuration defaults to the open position upon loss of pneumatic signal for fail-safe operation.
• Heavy-duty cast bronze body provides robust protection and corrosion resistance against fluid turbulence.
• Premium stainless steel trim reduces mechanical wear and extends the operational life of the valve.
• Equal percentage flow characteristic enables highly accurate and stable modulation across low and high flow rates.
• Exposed pneumatic actuator designed for seamless integration into existing pneumatic control loops.

Specifications

• Pipe Size: 0.5 inch (1/2″ NPT connections)
