The Johnson Controls V47AR-1 is a temperature-actuated, modulating water valve designed to regulate water flow in response to sensed temperature changes. This direct-acting valve opens proportionally as the temperature increases, providing accurate water flow control in cooling applications. The V47AR-1 features a large 1-1/2 inch pipe size and operates in a 75°F to 135°F cross-ambient temperature range, making it ideal for condenser water regulation in refrigeration and industrial cooling systems.
