    Valve Actuator - UK?

    Looking for a 2 way or 3 way valve actuator at a reasonable price (ie. <£200) to control the flow through solar matting. Any suggestions?

    You are about £400 adrift of an actuator valve, maybe a solenoid/diaphram type would do, that just in your budget.

    Yes, that is what I was afraid of! They seem to be < $150 in the US for the Jandy actuator. Can these be fitted to a normal ball valve? I can cope with the 24v control.

    Why not just have one sent over. Every pool builder has a few of these on the shelves.

    Re: Valve Actuator - UK?

    Thanks - getting one from the US may be the best idea. DO the valve actuators fit on a standard ball valve like this one, or do I need to get a Jandy valve also?

    No, you will need to get a jandy, or pentair valve.

    Any thoughts on whether this PVC irrigation valve would be up to the job?

    That is what I had in mind when I posted solenoid valve, I haven't personally tried it but the nice people at City irrigation are 10 mins up the road from me so I have spoken to them about utilising the valves.
    Give it a try..

    Thanks. I've ordered one. I'll update once I've installed it.

    Re: Valve Actuator - UK?

    Finally got around to testing the 2 port irrigation valve, and as a valve it works fine...

    However, I have plumbed it so that when it is open it "shorts" the solar heater feed and return pipework.

    Unfortunately I only get a small flow rate through the valve when open. The path of least resistance is actually through the solar heater and back to the pool return.

    To do properly I need two 2 port valves, with the opening of the flow through the solar heater synchronised with the closing of the valve for the solar bypass. This would not be safe as a malfunction in the opening valve would stop the water flow completely.

    So back to square one and trying to get a 1.5" three port diverter valve with an actuator for a reasonable cost. Anyone like to give me a price for US shipping to UK?

    thanks!

    Re: Valve Actuator - UK?

    To update this thread in case anyone else in the UK is looking for a 3 way valve.

    I ordered a Jandy Neverlube 3 way valve from a US ebay seller who had reasonable shipping charges to UK.

    I ordered an Intermatic valve actuator from a seller on Amazon.com (not amazon.co.uk). Again the shipping charges were reasonable.

    I already had a 24 VAC transformer I could use, but these are readily available on ebay as CCTV power supplies.

    All now installed and working well.

    One issue - UK pool pipe is normally ABS, however the Jandy valve is CPVC. The instructions state to only use "universal" glue and solvent. I couldn't find this anywhere online in the UK, so I ended up taking the risk and using normal cleaner, and normal Weld-On 725 glue. These do NOT say they are compatible with CPVC. However the joints appear solid, and do not leak. I'll update this thread if that changes!
