Thank you all.
Safety first, so we have dismissed the idea. We can choose for conventional gate valves (parallel slab type) or triple eccentric butterfly valves.
Hello, dear colleagues
For a big crude oil park (a lot of 48” valves) we have chosen gate valves slab wafer type. They are comparatively less heavy and not so big as others. We do hope they are also less expensive.
But. I have found only one manufacturer for this type of valve. And I wonder...
