Vokera 1789 heating valve

[DeanoM]

Hi all, I have had a prv valve replaced recently, and have just noticed a small drip coming from the pipework under the combi boiler. I've found out the part is a vokera 1789 heating valve. The leak is by the square part of the valve. I'm not great at plumbing so I'm just wondering if the square end can be tightened or whether I need a new valve. Cheers all.

No they’ve turned the valves off to fix the prv and then they’ve turned it back on and it’s started leaving valves need replacing
