Apologies for cross posting, but I wanted to get an operators point of view on the question below. Cheers.
I've had a question from a manager, asking what I thought about parallel slide valves in HC isolation service.
I don't think they're a good idea in HC services since they are only leak tight whilst there is upstream pressure. Lose the pressure and their ability to isolate effectively is compromised.
Having said that, it got me thinking whether they might indeed be used in such services. To my knowledge, parallel slides are primarily used in steam and hot condensate services... but I could have a skewed view.
I would appreciate your experiences.
Thanks in advance.
