As part of the steam cycle part of two Energy from Waste plants, we were asked to provide a number of valves including gate valves, globe valves, screw down non return valves, steam traps, control valves & safety valves. These covered ANSI class 800, 150, 300 & 600 in A105 Carbon Steel, WCB & WCC Carbon Steel and 316L Stainless Steel.
The first batch of manual valves that were required urgently, were supplied to our client as a priority on a fast track lead time. We then sized and specified control & safety valves on a longer lead time.
As part of this project we also specified and supplied two specially engineered knife gate valves for use on an abrasive service. These had special extended yokes to allow the operator access to the hand-wheel from under a silo with a 2 metre radius. The knife gate valves also had a special locking facility and visual indication to show how much the valve was open in % increments.
