Operating principle of electric ventilating type butterfly valve
Electric ventilating butterfly valve is built-up by electronic type quarter-tum actuator and ventilating butterfly valve. Because of the mechatronics structure design, it has the functions of inside servo operating, aperture signal position feedback, position indication,and manual manipulation. It has virtue of strong function, reliable performance and accurate control. It use AC220V or AC380V voltage as power to accept the(4-20mA or 1-5VDC)current signal or voltage signal which input by controlling system and then can operating under the controlling. And to accomplish the proportional control or on-off control of process fluid medium.
The matching actuator parameters are as follows:
The valve with small driving torque, on-off flexible and easy to operating
Can effectively avoid the stuck phenomenon which caused by thermal expansion
Short structure size, light weight and easy installation
Weld by steel plate
Setting an oil sealing ring on the valve body, without any visible gap between it, and small leakage rate.
The FRYQ+BW part-turn actuator achieves the 90 degree on-off operation on the large diameter and torque of butterfly valve and ball valve by add a double reduction based on the structure of the IQ multi-turn actuator, and torque range is 1000NM-63000NM.
◆ Sturdy construction,using dual-sealing,and can anti-water and dust(IP67/IP68-2M,48 hours)effectively when filed connection
◆ Three-phase, single-phase and direct current power supply actuator
◆ As the built-in data recording mechanism of the standard function
◆ Compatible with the IrDATM standard .Make the local and remote analysis on the actuator through insight PC software.
◆ Concise,easy to control,and indication functions.
◆ Multi-language text display screen displaying the state and setting.
◆ Simple torque and position control ,enchancing the reliability
◆ Flexibility of comprehensive control and indication.
◆ Optional specification of water proof and explosion proof type.
