Valve for sand application

[nur12]

Hi,
Which kind of valve would you suggest for sand application (not slurry, just crude oil / water mix with a small fraction of sand)? Our valves started to leak (even with sealant), so we try to replace it. We want to use a gate valve, but are concerned that the bottom seating area will simply fill with sand and than not seal. Is there some kind of valve specifically designed for high sand service (may be, with backflush capability in the seating area)? What do you use in the similar applications?

 

It depends also on your pressure but normaly rubberlined valves perform better within abrasion if the pressure is not higher as +/- 16 bar a stainless steel disk and nitrile liner (NBR BUNA N) will be sufficiant the best way to mount these valves is with horizontal shaft so the disk is able to "clean" the liner
