Parker Hannifin’s mechanical flange system for machines and plants − the HPF-Parker High Performance Flange System − has gained DNV GL approval for marine applications. This certifies the use of Parker’s HPF in hydraulic systems for injection moulding machinery as well as in hydraulic and mechanical presses.
This range of products meets the growing requirements of construction, especially for the navy, press manufacturing, injection moulding and mobile work equipment industries. It dispenses with the need for error-prone and time-consuming welding processes and has outstanding high pressure and vibration resistance.
The HPF is a form-fit connector system. In industrial applications, it provides the ideal replacement for welded pipe connections that are subjected to the highest loads. The HPF system consists of a hardened flange with lock ring contour, an HPF insert (with O ring recess or as a flat-sealing version) and seals on both port and pipe ends to ensure a gas-tight connection. Pipe flaring is effected in a tulip shape and has no sharp edges. Uniform loading of the surfaces in the whole flange area is achieved with this technology, resulting in very high break resistance.
The forming process is carried out utilising Parflare machinery, which provides hydraulic axial compression. Even large format tubes can be simply and quickly handled, thanks to the integrated pipe stop, exemplary ergonomic design and high operating convenience. Apart from its speed of process, HPF technology saves pipe testing and cleaning, processes that are time-consuming and costly compared to conventional welding.
Hydroformed tube valve body for diaphragm valves
Hydraulic systems & components
One of the most common necessities for manufacturing pharmaceuticals, cosmetics, food and beverages are diaphragm valves. What used to be a dull two-way race between forged and cast body variants is now being challenged by an exciting, ground-breaking technology. The hydroformed, light-weight diaphragm tube valve body will change the way you think about plant design and operation.
