Description

TruDesign Logo

TruDesign Ball Valves are designed and made in New Zealand for use in marine applications above and below the water line.

  • The body of the Ball Valve is manufactured from a glass-reinforced nylon composite.
  • High impact and tensile strength result in a light weight unit, free from corrosion and electrolysis issues.
  • The ball and sealing rings utilise a PTFE polymer to ensure a smooth action, and continuous ease of operation over many years.
  • The Ball Valve is available in  BSP  thread form and can be locked in the closed position for use on toilet waste outlets.


  • Immune to corrosion and electrolysis – Long life with no concerns over decreased performance due to corrosion
  • Chemical resistant – Impervious to diesel, petrol and antifouling paints
  • UV resistant – Will not degrade or discolour with ultraviolet light from the sun
  • Large operating temperature range (-40° to +110°C)
  • High quality surface finish – Will not discolour with green film as similar bronze fittings do
  • Approved by IMCI & Bureau VERITAS to ISO standard 9093-2 when used with TruDesign Skin Fittings
  • Complies with ABYC H-27 when used with TruDesign ABYC collar and TruDesign Skin Fittings

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.
  • An alternative T Handle is available for use where space is at a premium.

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.
For sealing any TruDesign composite fittings  you can use any of the following:

3M 5200
3M 5200 FT (Fastcure)
Sikaflex 291i
Loctite 55 Pipe Sealing Cord
Standard PTFE thread tape

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

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.

Are TruDesign Ball Valves certified ?

Yes. The TruDesign Ball Valves are Certified by the International Marine Certification Institute (IMCI) and Bureau Veritas to ISO 9093-2. Certificates can be downloaded from the Document section above.
