P10BC-7C Johnson Controls Pressure Control

Overview

The Johnson Controls V47AC-4C is a temperature-actuated modulating water regulating valve designed to control the flow of water or glycol solutions to maintain optimal operating temperatures. This commercial-grade, direct-acting valve operates efficiently without requiring an external power source, adjusting fluid flow proportionally in response to sensed temperature changes.

Features

• Self-powered operation that requires no external electrical connection.
• Open waterways with no close-fitting sliding parts to minimize fouling or sticking from water contamination.
• An isolated range spring design that avoids contact with the fluid to prevent corrosion.
• Easy manual flushing capabilities to clear out accumulated system debris.
• A robust design engineered to minimize chatter and water hammer during operation.

Specifications

• Pipe Size: 3/4 inch NPT
• Connection Type: Threaded, angled body style
• Valve Action: Two-way forward acting (opens on temperature increase)
• Operating Temperature Range: 160°F to 230°F (71°C to 110°C)
• Temperature Bulb Size: 11/16 inch diameter by 3-1/4 inch length
• Maximum Supply Water Pressure: 150 psig (1,034 kPa)
• Maximum Water Temperature: 170°F (77°C)

Applications

• Hydronic heating and cooling systems, including commercial fan coil units and unit heaters.
• Industrial heat exchangers used to maintain stable operating temperatures for internal combustion engines and air compressors.
• Cooling systems for hydraulic equipment to prevent the overheating of hydraulic oil.
• Condenser applications focused on economic fluid recovery or managing restricted water usage.
