A dual plate lug type non-return valve is a versatile valve designed to allow unidirectional flow and prevent backflow in pipelines. It features two spring-loaded plates that open with forward flow and close rapidly upon flow reversal, effectively reducing water hammer. The lug-type design includes threaded lugs for secure installation between pipeline flanges, offering easy installation and removal for maintenance. This valve is ideal for applications in industries such as oil and gas, water treatment, and power generation, where durability, compact design, and efficient flow control are essential. Its robust construction ensures reliable performance in high-pressure and high-flow environments.
