V47AT-2C Johnson Controls MODULATING Valve

Overview

The Johnson Controls V47AT-2C is a PENN V47 series temperature actuated modulating water regulating valve designed to maintain optimal fluid temperatures in commercial and industrial HVAC and heating or cooling systems. This 2-1/2 inch, two-way forward-acting valve opens on a temperature increase at the bulb to regulate the flow of water or glycol solutions, making it ideal for managing operating temperatures in heat exchangers, internal combustion engines, air compressors, and hydraulic systems.

Features

• Pressure balanced valve design minimizes chatter, water hammer, and fluctuations due to water pressure variations
• Designed without close-fitting sliding parts in water passages to prevent clogging and wear
• Built-in range spring does not come into contact with the cooling water to ensure long-term reliability
• Provides smooth temperature modulation with free movement of all internal parts
• Allows for easy manual flushing when required and withstands high hydraulic shock without damage

Applications

• Temperature control for industrial heat exchangers, air compressors, and hydraulic oil systems
• Maintaining optimum operating conditions for internal combustion engines
• Condenser water regulation where expensive fluids are recovered or fresh cooling water is restricted
• Process temperature monitoring such as managing paint temperatures on industrial printing machines
• Commercial HVAC and hydronic temperature regulation including swimming pools and commercial building loops
