Our purpose built facility allows testing on valves in controlled conditions such as this PR-2 test carried out on a Type H choke at temperatures down to -50ºF (-43°C).

 

Flow testing of valves in a purpose built flow loop can verify product design and assure that each N-Line Valve will provide its predicted performance.
