Check Valve (Non-Return Valve): Types, and Pricing

  Introduction A check valve , also known as a non-return valve (NRV) , is a mechanical device that allows fluid to flow in only one direction, preventing backflow. It is commonly used in pipelines, water supply systems, industrial processes, and pumps to maintain directional flow and prevent equipment damage due to reverse flow. Check Valve Symbol The check valve symbol used in engineering diagrams consists of a valve body with an arrow indicating the permitted flow direction and a barrier preventing reverse flow. It is commonly seen in process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs). Types of Check Valves (Non-Return Valves) There are several types of check valves (NRVs) designed for specific applications: Swing Check Valve – Uses a hinged disc that swings open with forward flow and closes when the flow reverses. Dual Plate Check Valve – Features two spring-loaded plates that automatically open and close with the...
