Monitored Ball Valve
Designed and made in New Zealand for use in marine applications above and below the waterline, our Ball Valves are IMCI and Bureau Veritas approved to ISO standard 9093-2. They also comply with ABYC H-27 500Lb standard. 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 9093-2. - TruDesign ¾”, 1”, 1¼”, 1½”, 2” and 3” Thru Hull’s, Ball Valves and Tail assemblies comply with ISO 9093-2 certification. The ½” does not comply. ABYC 500Lb load test standard. TruD...
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.
Identification of threads BSP or NPS ?
Tru-Design manufacture these marine fittings with two types of threads: BSP British Standard Pipe for the European market. NPS National pipe straight for the US market. Each threaded fitting wi...
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...
What sealant can I use on TruDesign threads ?
Thread sealing options: - 3M 5200 - 3M 5200FT (fast cure) - Sikaflex 291i - Sikaflex 591 - Loctite 5331 - Loctite 55 Pipe Sealing Chord - 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 ...
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: #3M 5200 #3M 5200 FT (Fastcure) # Sikaflex 291 # Sikaflex 591 # Loctite 5...
Can you fit TruDesign Ball Valves to bronze or Stainless 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 ...
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 ...
