VG7443LT+3008B Johnson Controls Valve and Actuator

Overview

The Johnson Controls VG7443LT+3008B is a factory-assembled 2-way, normally closed globe valve and pneumatic actuator combination designed to regulate the flow of hot water, chilled water, and saturated steam in HVAC systems. It features a cast bronze body with durable stainless steel trim and is equipped with a V-3000 pneumatic actuator to provide precise modulating control and fail-safe operation.

Features

• 2-way, normally closed (NC) fail-safe configuration
• Cast bronze body for superior corrosion resistance and long service life
• Stainless steel trim for enhanced durability and reliable seating
• Equal percentage flow characteristic for precise modulation and stable control
• Push-down-to-open (PDO) actuator action
• Rugged die-cast actuator enclosure
• Long-life replaceable ring packing for high reliability

Specifications

• Pipe Size: 3/4 inch NPT
• Flow Coefficient (Cv): 7.3
• Spring Range: 3 to 6 psi
• Maximum Supply Air Pressure: 25 psig
• Static Pressure Rating: ANSI Class 250
• Fluid Temperature Range: 35 to 338 degrees Fahrenheit
• Maximum Saturated Steam Pressure: 100 psig

Applications

Engineered for use in commercial and light industrial HVAC hydronic systems where reliable, modulating flow control is required. Common applications include variable-flow coil control, fan coil units, air handling units, heat exchangers, and terminal heating or cooling coils.
