Johnson Controls V146EK-1 Regulating Valve

The Johnson Controls V146EK-1 is a professional-grade two-way pressure actuated water regulating valve engineered for critical head pressure control in systems with water-cooled condensers. Designed with a 3/4" union sweat connection, this valve is built for high pressure water applications up to 350 psig, making it a reliable solution for high-rise buildings and demanding industrial environments. The V146EK-1 utilizes a Style 46 pressure element featuring a 30-inch capillary and a 1/4" flare nut for precise refrigerant sensing. With an adjustable opening point range from 70 to 260 PSI, this valve provides versatile refrigerant head pressure control for standard non-corrosive systems. Its pressure-balanced design ensures a consistent setpoint by resisting fluctuations in water supply pressure. The internal components are constructed with corrosion-resistant materials, and the take-apart design allows for streamlined servicing or valve flushing without the need to pump down the refrigeration circuit.

• Stable Head Pressure: Automatically modulates water flow to maintain optimal condensing temperatures as load conditions vary.
• High-Pressure Capability: Robust construction rated for 350 PSI water pressure, suitable for advanced hydronic loops and urban infrastructure.
• Service Accessibility: Accessible range spring and take-apart construction allow for maintenance and cleaning without removing the valve body from the piping.
• Universal Compatibility: Designed specifically for non-corrosive refrigerants utilizing a high-quality copper alloy body and internal sensing bellows.
• Field Adjustable: Features an easy-to-access manual flushing mechanism and a wide PSI opening point adjustment to match specific system requirements.

• What is the maximum water pressure this valve can handle? The Johnson Controls V146EK-1 is rated for a maximum system water pressure of 350 psig.
• Is this valve compatible with corrosive refrigerants? No, this specific model is designed for use with standard non-corrosive refrigerants only.
• How do you adjust the opening point on the V146EK-1? The opening point is tuned using the range adjustment screw located at the top of the valve assembly, covering a refrigerant pressure range of 70 to 260 PSI.
