D941W Electric ventilation valve 


 LDR type, HQ-or all-electronic PSQ-type rotary electric actuator is O-type ball valve drive, the use of integrated design, it AC220V power supply voltage for the power, directly accept a unified standard signal (4-20mA, 0 -10mA or 1-5VDC ,0-10V DC), this input signal into a corresponding displacement to angular displacement (0 ~ 90 °) movement, change valve opening, so some of the input signal corresponding to a certain position opening, the proportion of action to achieve. Two switching for receiving AC220V or AC380V power, achieved by reversing the motor switching, while the output valve position indication signal is a high precision, high performance, high reliability products. 


 Uses and Features 
 D941W Electric ventilation valve with the valve body using the same material processed into ring, using electric or pneumatic drive. Body temperature with the selection of its application, depending on the nominal pressure ≤ 0.6MPa, generally applicable to industry, metallurgy, environmental protection, adjust the media flow pipe for ventilation purposes. 
 Its main features are: 
 1, novel design, reasonable, unique structure, light weight, open and close quickly. 
 2, operating torque is small, easy to operate, saving smart. 
 3, the use of suitable materials to meet the needs of low, medium, high temperature of the different media, and corrosive media, etc.
