	Fact Sheet Pressure Control Valve   Control Valve In many situations our self-cleaning filters and Filterpumps will work without maintenance and the filter is kept clear by the self-cleaning mechanism. However in some situations the filters may block without the control valve fitted. When might you need it? Where there are high levels of suspended solids, or where there is a lot of grease and fat in the liquid to be filtered. In these situations the self-cleaning filters may block. Without a control valve the filter has to be manually cleaned.   Control Valve         Data Sheet                 Typical Applications Primary effluent Final effluent Agricultural dirty water systems Dewatering of lagoons             How does it work? The valve continually monitors the pressure within the filter compared to the surrounding liquid. If suspended solids are beginning to build up on the filter screen faster than the self-cleaning jets can clear it the valve throttles the output of the pump slightly. This means that there is less water being sucked through the filter and the self-cleaning mechanism is able to cope with the increased solids loading without blocking. If the solids levels in the water decrease, the valve opens, allowing the pump's output to return to normal, but if they continue to increase, the valve throttles the pump even more so that the filter does not block. Construction The valve, which has a 50mm orifice, is constructed entirely of stainless steel with the exception of the diaphragms. It consists of a stainless steel body with 2 balancing rolling diaphragms, which almost eliminate friction losses. There is a larger sensing diaphragm, one side of which is open to the environment; other side connects to the Rotorflush Filter. In operation the valve normally remains fully open allow the Rotorflush Filterpump to give full output. The valve has been carefully designed so that when used with the company's coarse screened strainers solids in the water do not affect it It may well find uses in other applications where a valve is required that is not affected by solids in the water and only a small force is available to open and shut the valve.. The valve can shut off a flow of liquid with a pressure of 10 bars with only a requirement for 50mb pressure differential across the sensing diaphragm.     FAQs     ?
