Frequently Asked Questions

  • Can I remove the handle from a TruDesign Ball Valve?

    Yes To aid installation in confined spaces it may be useful to remove the handle from the Ball Valve. To do so follow the steps below: # Remove the flush screw cover from the top of the handle (next to the TruDesign logo) with a sharp knife or small flat headed screw driver. # With a Phillips head screwdriver remove the Stainless screw # Remove the handle by pulling away from the valve body. # Ensure the handle is put back on the Ball Valve after installation. Reattach the stainless steel screw then push the screw cover back on the handle.

  • Do TruDesign Ball Valves require lubrication ?

    No. The TruDesign ball valves are manufactured with a Teflon impregnated Ball running on Teflon rings, so no lubrication is required. It is good practice to turn the valve handle every few months to keep the movement free but there have been several examples where TruDesign Ball Valve handles have not been turned for over 12 months and they still function fine.

  • Can you fit TruDesign Ball Valves to bronze skin fittings ?

    Yes TruDesign Composite ball valves can be screwed onto an approved bronze skin fitting. First the thread on the bronze skin fitting must be identified to match the TruDesign Ball Valve (either BSP or NPS). In the case of an old existing bronze skin fitting you must check that the bronze is not pitted or corroded from electrolysis and is in good mechanical condition.

  • What sealant should I use between a bronze skin fitting and a TruDesign ball valve ?

    The same options as you would use for sealing any TruDesign composite fitting to a TruDesign composite Ball Valve: # 3M 5200 Fastcure # Sikaflex 291i # Loctite 55 Pipe Sealing Cord # Standard PTFE thread tape

  • Can I screw a tapered fitting into a TruDesign Ball Valve ?

    NOT RECOMMENDED! The TruDesign Ball Valves have parallel threads and only fittings with parallel threads should be screwed into them. This is a very important issue as parallel threads allow for maximum engagement of the two threads and this is required for maximum strength and sealing. TruDesign have conducted many hours of load testing to gain both IMCI and Bureau Veritas approvals – which will not be covered if fittings with tapered threads are used.
