V47AE-13C Johnson Controls MODULATING Valve

Overview

The Johnson Controls V47AE-13C is a temperature-actuated modulating valve designed to regulate the flow of water or glycol to maintain a desired temperature. Part of the PENN V47 Series, this valve utilizes a pressure-balanced design that balances the valve against both gradual and sudden water pressure changes, ensuring stable operation. The valve action is designed to open on a temperature increase at the sensing bulb, making it ideal for heating and cooling control systems.

Features

• Pressure-balanced design employs synthetic rubber sealing diaphragms to balance the valve against water pressure variations and protect against high surge pressures.
• Sediment and corrosion protection by sealing cooling water away from the range spring, guides, and internal sliding parts.
• No close-fitting sliding parts in water passages, which minimizes the risk of stuck valves or hysteresis caused by contamination.
• Smooth temperature modulation due to the free movement of all parts.
• Built-in design features that minimize chatter and water hammer during operation.
• Easy manual flushing capabilities by lifting the lower spring guide without affecting the pre-set valve adjustments.
• Highly durable construction consisting of only five metal parts coming into contact with the water.
