V47AC-8C Johnson Controls MODULATING Valve

Overview

The Johnson Controls V47AC-8C is a self-contained, temperature-actuated modulating valve designed to automatically regulate the flow of water or glycol to maintain a desired temperature without requiring an external power source.

Features

• Direct-acting operation requires no electricity or external controls.
• Durable cast brass body provides strong corrosion resistance.
• Pressure-balanced design protects the valve against sudden pressure changes and high hydraulic shock.
• Internal design isolates the range spring from water passages to prevent sedimentation.
• Equipped with a removable bypass plug for flexible flow configuration.
