Self-balancing valve Overview: ZL47F-16 self-balancing valve, the main valve is an automatic adjustment and manual adjustment of valve components. Their use of media pressure change as a driving force, automatically adjust the balance of the branch line flow, accurate and stable flow, but also has opening instructions, lock, turn off, and other functions. Suitable for "heating, air conditioning and other non-corrosive media flow control run-time adjustment, you can make the system automatically constant flow setpoint required self-balancing valve main technical parameters: Model Nominal pressure Shell test pressure Sealing test pressure medium medium temperature ZL47F-16 1.6MPa 2.4MPa 1.76MPa water, oil, non-corrosive liquids 0 ~ 100 ℃ Self-balancing valve main dimensions: DN 15 20 25 32 40 50 65 80 100 125 150 200 250 300 350 Note l 110 110 115 160 200 215 230 275 290 310 350 430 520 635 670 DN15 ~ 25 threaded connection H1 72 72 81 108 138 138 143 170 193 208 254 289 325 357 372 H2 70 70 74 91 147 147 154 189 211 227 260,303,367,430,495 flow control m3 / h 0.1 ~ 1 0.1 ~ 1.5 0.2 ~ 2 0.5 ~ 4 1 ~ 6 2 ~ 10 3 ~ 15 5 ~ 25 10 ~ 35 15 ~ 50 30 ~ 80 40 ~ 180 100 ~ 300 150 ~ 500 200 ~ 700
