A valve driver is a device used to operate a valve and connect it to a valve. The device can be driven by a power source of manual, electric, pneumatic, hydraulic or combination forms, and the motion process can be controlled by the size of stroke, torque or axial thrust. Valve Control Actuators Choice of valve actuator to fully understand the type and performance of the valve actuator, depending on the type of valve, the working specifications of the device, and the position of the valve in the pipeline or device.
The valve actuator can be divided into two kinds of straight stroke and angular travel according to the movement mode. The direct travel drive device is a multiple rotary valve driver, which is mainly applicable to all kinds of gate valves, globe valve and throttle valve, and so on, Valve Control Actuators the angular stroke drive device, which is only a part of Rotary 90° turning angle, is mainly applicable to all kinds of ball valves, butterfly valves and so on.
The valve drive can be divided into manual (handle handwheel type, Spring lever type) according to energy form. Electric (electromagnetic, motor-type), pneumatic (diaphragm type, cylinder type, vane type, air engine type, film and ratchet combination), liquid (hydraulic cylinder type, hydraulic motor type), linkage (electro-hydraulic linkage, gas-liquid linkage) and other forms.
Valve driver is suitable for two-pass, three-way VB-3200 series and VF-3200 series dn25-dn52 regulating valve.
Valve Drive Features
1.24V AC voltage synchronization can be reversed to achieve.
2. The use of small-stroke switch limit
3. Fireproof ABS plastic Housings.
4. Convenient on-site installation.
5. Apply the direct stroke control valve under 23mm.
Valve actuator is a reversible synchronous motor drive, valve stem up or down to open and close the valve. When the valve fully open or full off, the valve drive to produce a reaction force, Valve Control Actuators so that the valve drive internal micro-switch power off, Valve drive to stop working. The valve driver can open the valve when it receives the control signal and can stop at any point stably without the signal.
