V148AL-1C Johnson Controls Valve

Part number V148AL-1C from Johnson Controls, listed in Valves & Process Control. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls V148AL-1C is a heavy-duty, 3-way, pressure-actuated water-regulating valve designed to regulate water flow and control refrigerant head pressure in systems with single or multiple water-cooled condensers. Specially built for high-pressure environments like high-rise buildings, it modulates water between the condenser and a bypass line to meet precise cooling demands under normal operating conditions. It features a take-apart construction that permits easy access to the valve interior without removing the valve from the refrigeration system or pumping it down. Features Pressure-balanced design resists changes to the setpoint caused by gradual or sudden water pressure adjustments. Constructed from corrosion-resistant internal parts, including a monel (nickel-copper alloy) seat and disc holder, alongside brass components to promote a long operational life. Equipped with an accessible range spring that allows for easy manual flushing. Utilizes an adjustable opening point that can be easily set within a specific refrigerant pressure range. Specifications Valve Size: 1 inch Body Style: Three-Way Maximum Water Pressure: 350 psi (24.1 bar) Maximum Refrigerant Pressure at Bellows: 320 psi (22.1 bar) Opening Point Adjustment Range: 145 to 190 psi (10.0 to 13.1 bar) Factory-Set Opening Point: 165 psi (11.4 bar) Throttling Range: 70 psi (4.8 bar) Inlet and Outlet Connection: 1-inch Union Sweat Pressure Connection: 1/4-inch Flare capillary Media Temperature Range: -4°F to 170°F (-20°C to 77°C) for glycol/water or liquids with low freezing points Material: Copper alloy body (contains lead; not for use with drinking water) Applications Designed primarily for commercial HVAC systems to control coolant media flow through water-cooled condensers. Ideal for high-pressure water applications up to 350 psi, such as those found in high-rise buildings or large commercial structures. Suitable for use with standard, non-corrosive refrigerants (such as R-22 or R-410A systems depending on pressure thresholds) to maintain proper refrigerant head pressures. Applicable in commercial hydronic cooling and industrial refrigeration setups requiring modulated bypass water flow.
