In the quest to demonstrate proper check valve opcra-tion for compres-sor and pump sta-tion applications, Cameron has rolled out its ENTECH™ DRV-BN non-slam nozzle check valve. Designer goal was a check valve that could operate effectively during horizontal operation as well as provide proof of its operational ability prior to installation. The combination of the company's engineering, product knowledge and application experience led to the design and production of the DRV-BN nozzle check valve which completed stringent API 6A PR2 and API 6D testing in 2011. Using a friction-free, uniquely weighted annular disc, together with a specially tailored spring mechanism, the check valve prevents reverse flow and provides end-users with field-tested assurance of successful operation. The type DRV-BN nozzle check valve is used in applications such as water, oil and LNG pump stations as well as in gas compressor stations. It is a large bore valve designed for compressor and pumping stations from 16-inch diameter and above, www.c-a-m.com.
