supply duplex filter

High flow double filter for industry---Introduction1.Material:stainless steel, carbon filter;2.Application: This filter is widely used in metallurgical machinery , mining machinery , heavy-duty machinery etc hydraulic system;3.Structure: Switching valves(1 piece);pressure gauges (2pcs);Differential pressure transducer(1 piece);Housing and filter element(2pcs);Balanced valve (1 piece);gasket and O-ring(2sizes ,2pcs);asbestos pad(2pcs);flat gasket,bolts and nuts(16sets);4.Working principle: There is only one filter to operation in normally work . You can not stop the system then open the pressure balance valve and roll reversing vales .switch to another filter to work , when the filter pressure loss exceed(more than 0.35 MPa ) and then clean or replace the filter element.High flow double filter for industry---Operational process1. Filter installation is completed , open the inlet and outlet valve of the filter , the system start to working;2. When the differential pressure transducer is alarm (differential pressure is achieved 0.35MPa), pls change the conversion valve and let another filter to work;3. Open the vent valve(on the upper cap) and blowdown valve (on the bottom cap), let the dust fluid drain off the filter completely;4. Open the upper cap of filter , take our the filter element;5. Clean or change the filter element , then install the filter element and upper cap;6. Closed the vent valve and blowdown valve and open the inlet and outlet valve of the filter;7. The best advantage of the duplex filter is when the element need to change or clean , don’t need stop system working.
