vb-7000 electric two way valve working principle
the vb-7000 electric two way valve produced and sold by woci valve group is driven by a reversible synchronous motor and has a magnetic clutch.the motor through the motor rotor and clutch produced by the magnetic action, can generate stable torque in the case of a halt.so when the motor can stop at any point stably when there is no current through, when the valve is fully open or fully closed when the magnetic clutch separation, stop adjustment.the signal sent by an incremental or proportional controller of the driver causes the motor to rotate synchronously or against time.
vb-7000 electric two way valve features 24v ac voltage reversible reversible motor. 1000 newton force. limit magnetic clutch. movement using gear transmission, the output gear screw group rotates around the central axis of the plane rolling bearings, the valve shaft is the use of the central screw pipe and the positioning of the wafer. valve actuator position indicator. fire-proof abs plastic cover. can be attached to the manual lever. site installation easy. suitable for direct stroke valve below 23mm.
1, the actuator used cast aluminum bracket and plastic shell, small size, light weight. 2, the choice of permanent magnet synchronous motor, and with a hysteresis clutch mechanism, with reliable self-protection. 3, suitable for a variety of control signals: incremental (floating point), voltage (0 ~ 10v), current (4 ~ 20ma). 4, with 0 ~ 10v or 4 ~ 20ma feedback signal (optional). 5, transmission gear with metal gears, greatly improving the service life of the drive. 6, low power consumption, output power, noise. 7, the valve body cast copper, cast iron, ductile iron a variety of materials to choose from, in order to suit different working media and temperature requirements. 8, the valve body has two threaded connections and flanges, easy to install. 9, the body structure of the form: two-way valve (single seat), two-way balance valve (balanced).
