Pipes & valves


system operation. Press-fit connections are designed to be secure. If the pipe is prepared correctly according to the press tool system manufacturer instructions, the connection is as strong as a welded or soldered connection. Many electro-hydraulic press tools have an auto-cycle feature that only


shuts off when the connection is complete, so there is no guessing if the pipe is fully joined or not. This secure fitting makes loosening caused by vibration or movement much less likely than with other pipe connection methods. Albion offers a range of press-fit valves that focus on providing all of these benefits for the installer and building maintenance teams. These are assembled and pressure-tested (with the ends in place) in the factory before being sent out, saving time on-site and providing peace-of-mind for installers that it is a secure connection.


The exception to this is the DZR brass press ball valve – the ART 55PRS – in which the press ends are an integral part of the valve’s body, i.e. adaptor fittings are not used. This approach reduces leak points, when compared to valves that use adaptor fittings, a significant benefit for large-scale projects where hundreds of valves may be fitted.


A key strength of using press-fit is that they make long-term system maintenance more manageable and less disruptive. With the press-fit approach, repairs can be made quickly and with minimal disruption to building users. Even if the pipe system is wet, press-fit connections can still be completed. Therefore, press fittings are highly suited to application in commercial and industrial facilities because there is no need to shut down a pipe system to perform maintenance, so operations don’t have to be interrupted. For specifiers, the ability to use press-fit systems with a range of pipe materials is critical. Press-fit valves can be used on a variety of pipe

materials such as, copper, stainless steel and carbon steel, regardless of the material of the valve.


Stainless steel fittings are becoming more popular with installers, possibly because the price differential between carbon and stainless steel is shrinking. Stainless steel is more often specified for buildings such as hospitals, due to its hygienic properties, which is a primary market for the construction sector. But the architectural trend towards exposed pipework may also be driving demand for stainless steel which is more aesthetically pleasing. Brass and DZR brass continue to be staples in the market, offering a range of benefits. Both are excellent options for potable water systems, and DZR is corrosion-resistant (making it useful for hard water areas, for example). Brass is durable while also being lightweight, making it suitable for a range of pipework projects including those that involve high-temperature water. It is also a cost-effective material that stands the test of time. Designers and installers must have a choice of materials for HVAC pipework. Building technologies are constantly changing, posing a challenge for those who have to deliver them. A range of press-fit valves that will work across a breadth of projects is an asset that can save time and capital cost in the short term. It will also provide peace-of-mind for building owners and managers since press-fit valves can be updated without the need to shut down a whole pipe system.


Valves may not be the largest piece of equipment to be specified for a building, but they are important enough to consider carefully. Valve technology has advanced to embrace a range of materials, fitting methods and functions, focusing on supporting quick and efficient installation. Our advice is to speak to us to get the best long-term outcomes.
