Need the best non leak motorised valve

[diode84]

Hello
My first post so hello everyone.
I put in my home system a few years ago and used Sunvic mo-mo motorised valves. The second one is leaking from the seal where the motor rotates the valve.
Can anyone recommend the best non leak motorised two way valve that will last a long time. It does not have to be motor on-motor off, a normal one would be fine.
Thanks

Myson seem to be a good choice as well

some Sunvic Mo-Mo valves will need a wiring alteration if you replace with a spring return valve, not all will but some will, usually just means isolating a wire, do you have a wiring centre with relays in it ? I am a Honeywell fan, but dont buy one from the tinternet or DIY stores, saying Honeywell equivalent, they are cheap Chinese rubbish

I would go Honeywell easy to get replacement syncron motors too. Seldom leak although like most valves they can start to stick as they get older.

Honeywell- I've had 3 in service here since 1991. Had to replace the drive motors but the actual valves are still working perfectly

No relays in wiring centre. I have ordered a Honeywell valve from Screwfix, I hope they are genuine, I pick it up tomorrow. I will look at its instructions and modify the wiring as needed.
Thank you everyone for the help, I know I will be back in the future.
