。 According to supply sample values, and referring to the interfaces' Marine valve 'of facilities, to check whether the flow rate of valve in the specification satisfied requirements. 2, choose suitable differential pressure range. 。 3, according to the calculated flow rate and differential pressure range and technical requirements to confirm the suitable Industrial Valves series, model. Stem flow valve pressure drop is equal to its office differential pressure range of minimum pressure drop value. Note: the pump head = dynamic flow balance valve pressure drop + other pressures of the system. Q: traffic stem valves, pressure differential stem default selection guide valve answer: 1, calculated by the water flow of the Industrial Valves. Calculation of water system resistance, it is concluded that the differential pressure valve demand reference, to confirm that the Industrial Valves differential pressure range. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
