Johnson Controls Pressure-Actuated Water Regulating Valve HVAC Control Valves & Actuators

The Johnson Controls V46 Series pressure-actuated water regulating valve is a self-contained modulating valve. It controls the flow of water or glycol to water-cooled condensers in refrigeration and HVAC systems. It senses refrigerant head pressure and adjusts water flow to match. This helps hold stable system pressure and avoids wasting water. It works on both open and closed water systems and needs no external power.

Key Features:

• Pressure-actuated modulating control: Direct-acting models open as refrigerant pressure rises. Reverse-acting models are also offered in the series.
• Adjustable opening point: Lets you set the valve for different refrigerant pressure ranges.
• Pressure-balanced design: Helps the valve hold a consistent setpoint through gradual and sudden pressure changes.
• Smooth, quiet operation: Free movement of the internal parts gives smooth modulation and helps limit chatter and water hammer.
• Durable construction: Water-contacting parts are corrosion resistant. Models for corrosive coolants are available with monel trim.
• Serviceable take-apart design: You can reach the valve interior without removing the valve from the refrigeration system or pumping the system down.
• Open water passages: No close-fitting or sliding parts sit in the water passages, so the valve keeps working in less than ideal conditions.

Applications: Water-cooled condensers, bypass service on refrigeration systems, ice machines, engine cooling, and general commercial and industrial cooling.

The valve is not intended for use on drinking water. Select the model that matches your required connection style and pressure range.
