Have you ever wondered why P-V valves are supposed to be non-hammering?

Please contact our CEO, Mr. Søren Bay Jensen for a thoroughly explanation and real life consequence of supposedly! “non-hammering” valves,

the root cause and some valve manufacturers track history.

IMO MSC Circ. 677 states –


In the case of high velocity vents, the possibility of inadvertent detrimental hammering* leading to damage and/or failure should be considered with a view to eliminating it.

and – Hammering” is rapid full stroke opening/closing, not intended by the manufacturer during normal operations – UN-QUOTE.

Has some manufacturer taken advantage of this vague wording?
