In the past, bulk storage systems have been used to house nitrogen on-site at the manufacturing plants, but this method of storage can result in a significant loss in revenue when all is said and done. So, what is the solution for plant owners? The answer begins with in-house nitrogen generation systems.

When selecting the pipes and valves to be included in a cooling system, it is important to understand the options available — and the possible outcomes associated with each selection. The selection process is often overlooked or is not given proper attention by designers and contractors. Many factors can impact the effectiveness, longevity and quality of the overall cooling system.

Just as sound can have negative effects on the human body, certain frequencies can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.
Valin provides outstanding solutions and are very responsive to our needs.
