Non Slam Axial Nozzle Check Valves designed and manufactured to specification by Europa Valve for a customer in the United States; Natural Gas Transmission, a company operating within the North American oil and gas industry.
During production, pup pipe pieces* were fitted to the check valves. This is a great way to allow rapid and higher quality welds. The result is a straightforward pipe-to-pipe weld on the same wall thickness, rather than trying to transition from the heavy wall valve body to a thin wall pipe and avoids all the associated heat treatment requirements in such a process.
Shown here are 16” and 20”, class 600 and 900, Non Slam Axial Nozzle Check Valves.
If you require any further information regarding this type of valve manufacture, please feel free to contact our technical department and we will be happy to assist.
*A pup is a short length of pipe that connects two piping components.

The check valve will be placed at the discharge section of a centrifugal compressor to eliminate backflow through the compressor. Should backflow occur, the compressor can experience damaging reverse rotation. Therefore, this is a very critical application and represents a typical installation location and requirement for Europa Non Slam Check Valves.
The presence of a discharge check valve also provides the benefit of isolating each of the antisurge recycle loops.
This non-slam check valve will go into service for more than 20 years without the need for maintenance or servicing whatsoever.
