What causes trv's to leak?

Hi, I had a problem last year where two of my trv's were leaking, and the rest were showing signs of starting to leak around the pin, so I had to replace them all. They were only a few years old. I asked the person who fitted them today and he said it was caused by turning them on/off, up/down too often. They are designed to be set and just left otherwise frequent turning will cause the grease in them to dry out and they will leak. Is this true, because I want to be able to turn them off or down when I go out in the morning just leaving the bathroom radiator on for a few hours to dry my towel, and have a few turned up to maximum at the week-end to dry clothes. I don't really want to have some radiators on when I'm out particularly the lounge one which is huge. It just seems such a waste. Many thanks, Simon
