The model SV16WK-3/4-AC220V is an example in the table.
The order in the table is not suitable for SV1.6, SV2, SV3 series and type NSV6A.
Usage 1. The valve must install in horizontal pipe line under vertical position. The flow direction must meet the arrow direction in valve body. 2. The oil input voltage must meet rated input voltage showed on the label. Departure coil from valve when energized in coil is not permitted in order to avoid damage the coil. 3. According to valve with manual function, it must turn manual bar to open the valve before doing system air tightness in order to avoid to damage diaphragm. 4. When brazing the valve with connect tube in system, follow points are very important: a. Before brazing, coil must be departure and use wet fabric cover the valve body to avoid to damage valve part because of high temperature when brazing. b. It must avoid the brazing flame face to valve body. c. It is better to adopt low temperature type silver brazing bar. 5. According to valve with manual function. The manual bar must be turned to open the valve before doing system air tightness, in order to avoid to damage the diaphragm. 6. Coil must be set to the body when the current on.
