AnonymousWe now have delta valves at our facility… They work great, one year so far with zero issues..

AnonymousI have been using Swing Away of Hahn Clay with no problems!!! It requests maintenance like all the other valves but the cost is so much lower. There is a new system of Hahn & Clay called Chute Fixed that has no problems because the chute is fixed that means no movement of the drum and it doesnt use steam, and less maintenance because it doesnt have a lot of hydraulic parts like other valves.
