V146EK-1

The V146EK-1 model from Johnson Controls functions as a pressure-actuated water regulating valve, specifically designed for effectively controlling water flow in water-cooled condenser systems. It has a size of 3/4 inches and weighs 4.3 lbs, making it manageable for various installations. This valve connects via union (sweat) fittings of style 46, simplifying integration into existing pipe work.

The adjustment range for the opening point pressure spans from 70 psi to 260 psi, with a factory pre-set to open at 165 psi. This configuration allows users to customize operation according to system needs. It can withstand maximum refrigerant pressures of 370 psi and water supply pressures of 350 psi, showcasing robust performance capabilities.

The structure of the valve body is made from cast brass, offering durability and corrosion resistance. The valve stem is crafted from brass, paired with a Buna-N disc, ensuring effective sealing and longevity in service. Additionally, the sensing element consists of brass and phosphor bronze bellows housed in a brass cup, enhancing reliability.

Designed as a two-way valve, the pressure connection utilizes style 46, utilizing copper capillary with a 1/4-inch SAE female flare. The temperature range for the media is between -20 and 77 degrees Celsius, which accommodates a variety of refrigerants and ambient conditions. Overall, the Johnson Controls V146EK-1 valve precisely regulates water flow to manage refrigerant head pressure, making it a crucial component in efficient cooling systems.
