Monitored Ball Valve
TruDesign Certified Ball Valves are designed and made in New Zealand for use in marine applications above and below the waterline.
They are ideal for controlling inlet and outlet water requirements.
Position Monitoring allows remote monitoring of Ball Valve Position. The Position Monitoring circuit can also be used as part of an engine or generator start interlock to ensure these don’t start without cooling water available.
The body of the Ball Valve is manufactured in glass-reinforced nylon composite with high impact and tensile strength resulting 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 both BSP and NPS Parallel thread forms and can be locked in the closed position for use on toilet waste outlets.

Are TruDesign Skin Fittings certified ?
ISO 9093-2021 Small craft -TRUDESIGN Skin Fittings and Ball Valves comply with ISO 9093:2021 and certified by the International Marine Certification Institute (IMCI). For sizes ¾” through to 3” ...
How do I wire a Monitored Ball Valve with ignition interlock?
You can use the monitored ball valve to disable ignition of an engine until the valve is open (water intake open). This avoids possible engine running without coolant.
How do I identify BSP or NPS threads?
TruDesign manufacture marine fittings with two types of threads: NPS (National Pipe Straight) threads are common in the United States. BSP (British Standard Pipe) threads are widely used in Eur...
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...
Can I screw a tapered fitting into a TruDesign Ball Valve ?
NOT RECOMMENDED! 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 ma...
What sealant should I use between a bronze or stainless 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. TruDesign recommends the following sealants: Adhesive Thread Sealants: - Sika...
Can I fit TruDesign Ball Valves to bronze or Stainless skin fittings ?
Yes TruDesign Composite ball valves can be screwed onto an approved bronze or Stainless Steel skin fitting. First the thread on the bronze skin fitting must be identified to match the TruDesign ...
Can I run Petrol or Diesel through TruDesign fittings ?
YES and No TruDesign fittings (in both black and white) are suitable for contact with petrol & diesel fuels. NOTE: TruDesign Ball Valves, Aquavalves and Non-Return Valves should not be used in d...
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...
