Durapipe UK continues to expand its valve offering, and has recently provided a range of silicone-free valves, specifically developed for use in paint and ink applications in industrial markets. While silicone-based lubricants can provide excellent lubricating properties and longevity, in certain painting and inking applications the presence of silicone can be detrimental. Silicone-based paints and inks can adhere to the silicone components in the valve causing contamination issues, which could result in surface defects and a poor quality finish.
These valves are expertly cleaned within a bespoke clean room facility, conforming to ISO 14644-1 clean room standards, utilising a three stage chemical cleaning process, using ultraconic cleaning tanks, ensuring all valve components are free from any traces of silicone. The valve is then dried using a compressed air system and bagged within a dual skin silicone free package to prevent any contamination. In addition, a non-silicone lubricant is used at Durapipe for both ball and butterfly valves to maintain efficient operation over the lifetime of the system.
The company’s wide portfolio of valves can now be provided with silicone free components, including the VKD Ball Valve, VKR Metering Ball Valve, TKD 3 Way Ball Valve, FK Butterfly Valve and Dialock Diaphraghm Valves, which are all available in a variety of materials including PVC-U, SuperFLO ABS, CPVC, PP and PVDF.
