First, the digital lock balance valve uses of the valve is a balanced valve, suitable for all kinds of liquids pipeline system, it is an ideal new energy-saving valve. The valve has a scale figures, it can be transferred to any intuitive - position and lockable. The valve is mainly used in industrial and civil construction Ai mining piping systems. Currently there are hydraulic imbalance in some pipeline systems, balance provides the means to solve this problem, it can be accurately adjusted by the pressure drop and flow rate, liquid flow conditions to improve pipeline system, to pipe the liquid balance and energy conservation purposes. In the double-pipe network engineering, the application of this valve can still save energy, get better results. Second, the digital lock balance valve main performance and the use of standardized model SP15- (10/16) SP45F- (10/16) Remarks Test pressure 2.4Mpa (24kgf / m2) working pressure ≤1.6MPa (16kgf / cm2) working temperature ≤120 ℃ For medium water, oil and other liquids characteristic curve percentage range installation of trunk pipeline network, branches dry, indoor water trunk, branch riser and many boilers SP45F- (10/16) type main external and connecting dimensions (flange dimensions according to JB / 79-94 standard) DN LH 32 180 230 40 200 242 50 230 250 65 290 260 80 310 329 100 350 340 125 400 424 150 480 454 200 550 517 250 622 573 300 698 617 350 787 705 SPl5F- type main external and connecting dimensions DN ZG LSH weight kg 15 1/2 "100 27 128 1 20 3/4" 115 33 128 1.5 25 1 "125 46 130 1.8 32 5/4" 140 55 150 2 40 3 / 2 "1605518725
