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.
Features
- 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
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 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.
