Breakaway Couplings - are you getting the one you need?
Breakaway couplings are the life blood of connections between machines, often the saying we hear is "Just as long as they work and they are cheap" and we get that. Over the years we have been challenged to find a coupling that doesn't leak and DNP has answered that question for us. As an OEM you don't need any reason for the customer to have an angle with you.......
In hydraulic fluid power systems, power is transmitted through an enclosed circuit via fluid under pressure. Quick release couplings or QRC’s (also known as quick-action couplings, quick connect couplings, break-away couplings, just to name a few) are used to join or separate fluid conductors to or from a circuit.
There are just as many manufacturers as there are types of QRC’s. Thankfully, there is an international standard to which the manufacturers conform to. The International Organization for Standardization (ISO) specifies things such as the dimensional requirements and performance requirements and allocates an ISO number. Examples of these ISO numbers are ISO 7241 Series A, ISO 7241 Series B, and ISO 16028. Some manufacturers who produce QRC’s in this series are Ryco, Safeway, Parker, Eaton/Aeroquip, Faster, Hansen, Holmbury among others.
Many of these manufacturers release a cross reference chart in their catalogues to help in determining what other brands their QRC’s are interchangeable with. Some even release to-scale profile outlines for quick match up of a couplings physical size (The various ISO standard physical dimensions are only available as part of the full documentation available from ISO.org and must be purchased).
D.N.P Industriale Srl has been manufacturing DNP quick couplings for hydraulic systems since 1985.
Precision, innovation and reliability are the strengths that have made DNP a leading brand in the global industry of quick couplings. DNP produces Push Pull valves, screw valves, flat valves and special executions.
The 95% of their production is exported all over the world.
All products are manufactured in-house in DNP factories in Italy with constant monitoring of product because for DNP the quality is a goal that goes beyond the finished product.
DNP offers the widest product of hydraulic quick release couplings.
When identifying and replacing QRC’s it is helpful to try and find a part number or other identification marks that can be used to determine it’s ISO standard and series.
Lastly, it’s also important to point out that not all QRC’s comply to a particular ISO standard but many of the manufacturers have gone to the effort of making their own versions that are interchangeable with others. Finding any identifying marks can aid in locating a new genuine QRC or an equivalent QRC from an alternate manufacturer.
