Diverter Valve Overview Brochure

The Diverter valve was invented by SchuF in 1965. The first diverter valves were the simple Operating Principles > 1) outlet A only, combination of two or more piston or disc valves. Over the past 45 years, SchuF Fetterolf developed In its simplest form a diverter valve has oneinlet and two outlets or vice versa. When the medium flows through the inlet it can either be routed to 2) outlet B only, or 3) to both outlet A and Bsimultaneously. This is achieved by two pistons (or discs) that move into the valve body and cover all or part of the outlets from either side. This action results in a...

Dead space can lead to many unwelcome consequences. In plastic and polymer pro- duction, the medium can be contaminated by trapped particles, rendering it worthless. In the refinery, dead space can lead to accumulation of coke like particles, catalyst fines or clumps which necessitates back flushing and thereby reduces line capacity. > Traditionally, isolation valvesinterconnected with T-piece piping are used to isolate the process flow in one direction. This is achieved by using two ball valves and a T-piece as shown above. When one of the ball valves is closed and the medium contains...

SchuFs attention to quality and ensuring optimal valve efficiency is reflected in our use of finite element simulation analysis. These simulations enable us to advise the best valve design for a specific process. The example below shows the results of a valve simulation for a polymer like medium. Each flow line is colour coded to show how farthe polymer will have travelled in a given time. Deep blue shows how far the polymer would travel in the first 2 seconds, light blue in six seconds, green in 9 seconds, yellow in 13 seconds and so on. The simulation shows that there are variances in...

process. This part of the refinery includes equipment for isolation, steam injection, quenching, condensate, and draining. In addition to the equipment, a significantlength of piping is required. This in turn has to be kept clean and regularly maintained. All in all the initial capital outlay and ongoing operating costs are high. The Diverter valve is an ideal tool to reconstruct,replace or redesign a process or plant layout. It is also an essential ingredient in new plant design where capital cost and space are primary concerns. The picture below shows the piping, valve and space...

In December 2008, a major coal producer launched the first full scale commercial trial for a coal to liquid refinery based on the Bergius process. The plant was designed to produce 900,000 tons of gasoline, diesel and kerosene per annum. The Bergius process uses ground coal as feed, which is then processed under temperatures up to 500C and high pressure (to 240 bar). These operating conditions create a series of problems for equipment and in particular for valves. The control valves have tohandle pressure drops of up to 200 bar with a high solids content and high temperature. enters a star...
