1. Check Valve Purpose and function Prevents backflow by allowing fluid to move in one direction only. Opens with forward flow and closes automatically to stop reverse flow, protecting downstream equipment and maintaining system cleanliness. Key benefits System protection: reduces risk of backcontamination and damage from reverse flow. Equipment protection: guards pumps, valves, and gauges from reverse pressure and water hammer. Reliability: simple, robust design with few moving parts for consistent performance. Installation flexibility: designed to integrate with standard piping systems and common connection types. Performance: provides dependable, oneway flow with minimal pressure loss when open. Attributes to consider Function: oneway flow control to prevent backflow. Compatibility: suitable for use with standard piping connections; check model specifications for exact compatibility with your system. Size: available in multiple sizes to fit a range of piping diameters; select size based on your system requirements. Material: offered in materials chosen for durability and compatibility with typical fluids and environments; refer to the specific model for exact material options. Performance: designed to deliver reliable closure and consistent flow characteristics in normal operating conditions. Materials and sizes (model variations) This product line includes various sizes and material options; exact specifications depend on the chosen model. Consult the product datasheet or supplier for the available options in your application. Use scenarios 1) Residential water system with a well or booster pump to prevent backflow into the potable supply. 2) Irrigation or sprinkler system to stop water from returning to the main line when pumps cycle off. 3) Light industrial or processing lines where oneway flow is required to protect downstream equipment and maintain process integrity. Installation and handling notes Install in the direction indicated by the flow arrow on the valve body. Choose the appropriate size and material for the specific fluid and operating conditions. Follow all local codes and manufacturer installation guidelines for proper mounting, support, and maintenance.
