Acceptable instrument or computer output intermittent or continuous control signals to adjust the pressure, flow, level, temperature, humidity and other parameters. But also to adapt to various industries chemical, petroleum, metallurgy, electric power production process automatic control and remote control. Features: 1 actuator torque 1800N-6500N. Three floating-point or 0 ~ 10v; 4 ~ 20mA control signal. (2) body diameter DN50-DN150mm; pressure: PN1.6Mpa. 3 valve 2 ℃ ~ 140 ℃;. Steam valve 2 ℃ ~ 180 ℃ 4 modular stem stuffing using a spring loaded, self-adjusting "V"-rings. Without leakage. 5. Balanced body structure, high-pressure system to overcome the unbalanced force, pressure differential to adapt to situations. VB Series electric control valve, use of domestic drivers; Adaptation: VB Series thermostatic valve / electric control valve. Used in air conditioning, refrigeration, heating, ventilation, heating and other control systems. Acceptable instrument or computer output intermittent or continuous control signals to adjust the pressure, flow, level, temperature, humidity and other parameters. But also to adapt to various industries chemical, petroleum, metallurgy, electric power production process automatic control and remote control. Features: 1) actuator force 1800N-25000N 2) valve pressure PN1.6Mpa. 3) valve temperature 2 ℃ ~ 140 ℃; steam valve temperature 2 ℃ ~ 180 ℃ 4) There are two body through balanced, three-way split, three confluence. Diameter DN50-DN350mm. 5) combined spring loaded stem packing, self-adjusting "V"-rings. To prevent leakage. 6) actuator spring suspension structure. Cut off the power to protect the motor in case of overload, while maintaining a constant seal. 7) Two-balanced, unbalanced force to overcome the high pressure system (pressure 1.6MPa). Used in high value-added applications.
