Select the hydraulic valve

In the selection of the hydraulic valve, be sure to see the flow and pressure range, but also pay attention to the flow-pressure curve, if the selection is too small, often cause system pressure loss is too large, the system heat, if the selection is too large, wasteful economy. Two hydraulic valve sealing material optional Viton seals suitable for phosphate medium, NBR seals suitable for mineral oil medium, according to media actually used to select, Viton seal hydraulic valve to be more expensive. When selecting the best conditions for children member selected valve do performance testing, foolproof. Component selection, to the hydraulic schematic diagram of the respective valve type, each channel code, the tool code, each port of the code and the size of a good mark for the hydraulic valve design and proofreading.
