V246GR1-001C Johnson Controls Water Valve

Overview

The Johnson Controls V246GR1-001C is a commercial-grade, direct-acting, 2-way pressure-actuated water-regulating valve designed to control refrigerant head pressure in systems with water-cooled condensers. It automatically modulates condenser water flow in response to changes in high-side refrigerant pressure, ensuring optimal condensing temperatures, protecting compressors, and improving overall system efficiency.

Features

• No close-fitting or sliding parts in water passages, providing robust control in less than ideal conditions
• Pressure-balanced design resists changes to setpoint caused by sudden water pressure changes
• Take-apart construction allows access to the valve interior without removing the valve from the system
• Accessible range spring allows for easy manual flushing
• Corrosion-resistant internal materials promote long valve life
• Durable cast iron body with a rust-resisting finish

Specifications

• Valve Size: 1-1/2 inches
• Connection Type: ASME Four-Hole Flange
• Action Type: Direct Acting, Commercial
• Opening Point Range: 200 to 400 psi (13.8 to 27.6 bar)
• Maximum Sensing Element Pressure: 630 psi (43.4 bar)
• Maximum Water Pressure: 150 psi (10.3 bar)
• Maximum Water Temperature: 170°F (77°C)
• Sensing Fitting: 1/4 inch Male External Flare (Style 5)

Applications

• Designed for use with standard, non-corrosive, high-pressure refrigerants in water-cooled condenser systems
• Ideal for regulating the flow of conditioned water, sea water, or glycol systems to maintain optimal refrigeration system balance
• Commonly applied in commercial HVAC and refrigeration units where condenser water flow must be adjusted based on system load demands
