API 6d check valve

API 6d check valve

A check valve which is prominent used in wide range of industries to prevent backflow is an API 6D check valve. These types of valves are also full port swing check valves. With top entry access to all valve internals, thanks to closure which makes it easy for you to maintain and troubleshoot.

Adding to this, when it is open fully, it is the closure which takes responsibility to clear the path flow. With the same pressure ratings as ball valves, they are available in same pressure ratings, but have small sizes in the range NPS2 – 24 inches.

Because they exhibit excellent and unique characteristic, there are many functionalities which are delivered by API 6D wafer check valve. This is the reason why it is a trusted valve for operations of oil and gas, which in turn, ensure uninterrupted and full flow. Another functionality is that API 6D air compressor check valve offers tight closures under low-pressure conditions. This helps us offer low cost- or cost-efficient solution to backflow scenarios. Adding to this, it follows API 6D standards and ANSI B16.34 specifications.

Buy API 6d piston check valve from ADNOC approved suppliers at the best price in the middle east and India

Despite comprising unique characteristics, there are many advantages that one can grab by using API 6D wafer check valve:

  • To withstand severe shock of check valve services, this valve has a robust one-piece construction.
  • Allow rapid closure while minimizing slamming it is combined with balanced disc. This is an added reason for short distance of travel.
  • Another advantage of using API 6D piston check valve is that it can be installed both horizontally or vertically.
