Dry Break couplings – cheap doesn’t always mean economical (March 2013)
When specifying a Dry Break coupling the one area that is often neglected is the flow rate. According to Action Sealtite, this can be an expensive omission. The company makes the point that undersized couplings will not only perform incorrectly but an oversized coupling may lead to larger hoses, expensive adaptors and overall higher costs of ownership.
Action Sealtite can help customers specify the correct coupling for their application. When sizing the coupling to the application a smaller coupling can often be offered by sourcing a ball valve or butterfly valve design Dry Break, thus reducing the overall assembly costs.
Another option can be choosing a higher pressure-rated Aluminium Cleanbreak coupling against having to upgrade to stainless steel where the application allows. Again, a large cost saving can be made based on the ability to specify the coupling to the application and not settling for a ‘best fit option’, which can sometimes be the case when a supplier is restricted by the range available to them.
Action Sealtite comments that it sees it as part of the company’s service to work with customers on design and specification of their couplings to offer the most economical solution for the application in question. Action Sealtite adds that when choosing a Dry Break coupling the criteria for every application are different.
The company therefore stresses that this is why it is important to work with a company that understands the advantages of the different products available, and recognises what is important for the customer. It also needs to bear in mind aspects such as r restricted operating space, level of spill, low pressure drop, high working pressure, and the weight of the coupling or seal materials available. Action Sealtite recommends that users let its Dry Break team aid them in the process of choosing the correct coupling for the job.
