The Johnson Controls V47ND-2 is a temperature-actuated, modulating water valve designed to regulate the flow of water or other liquids based on sensed temperature. This direct-acting valve opens as the sensed temperature increases and closes as the temperature decreases, offering precise, proportional control. With a 1-inch NPT connection and a 45°F to 85°F opening temperature range, the V47ND-2 is ideal for cooling and temperature maintenance in industrial, commercial, and process systems.
