VG7241LT+3008E Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7241LT+3008E is a professional-grade bronze globe control valve assembly engineered for precise flow regulation in HVAC systems. This 2-way, normally open pneumatic valve features a 3/4-inch NPT connection and is primarily designed to regulate the flow of hot water, chilled water, glycol solutions, or low-pressure saturated steam in response to the demand of a controller. Equipped with an exposed yoke pneumatic actuator, this model ensures reliable, fail-safe operation.

Features

• High-quality cast bronze body and durable brass trim for corrosion resistance and longevity.
• Straight-through piping configuration with a 2-way normally open design.
• Equal percentage flow characteristic for stable modulating control that prevents hunting in the control loop.
• Spring-return pneumatic actuator ensures the valve returns to its open position upon loss of air pressure.
• Exposed yoke design allows for convenient field maintenance and visual stroke verification.
• Tested for over one million cycles to ensure long-term durability and operational life.

Specifications

• Valve Size: 3/4 inch
• Connection Type: NPT (Female NPT)
• Flow Coefficient: 7.3 Cv
• Actuator Type: Pneumatic (V-3000 series compact actuator)
• Spring Range: 9 to 13 psi
• Pressure Rating: ANSI Class 250
• Maximum Saturated Steam Pressure: 15 psi WSP
• Maximum Water Pressure: 400 psi WOG up to 150°F
• Media Temperature Range: 35°F to 248°F (2°C to 120°C) for water; maximum 284°F (138°C) for steam

Applications

• Designed for heating, ventilating, and air conditioning (HVAC) systems.
• Ideally suited for air handling units (AHUs), terminal units, baseboard radiators, and convectors requiring precise modulating control.
• Used in water, glycol, and low-pressure steam applications where fail-safe normally open operation is necessary to protect sensitive coils and equipment.
