HEP pneumatic valve positioner

- HEP electricity Gas pneumatic valve positioner with pneumatic valve position transducer ( Built-in PTM) From the control system is a kind of accept - MA dc current signal is converted into drive actuator gas signal, thereby to control the pneumatic valve position of the device. And the pneumatic valve position transducer ( Built-in PTM) To convert the current open - MA dc current signal. Not another stent installing pneumatic valve position transmitter, only need a installation board can complete compressors installed. The electric pneumatic valve positioner, air filtration pressure reducer, pneumatic valve position transmitter, greatly improving the efficiency. Explosion-proof property: this safety type explosive-proof grade ia Ⅱ CT flameproof explosion-proof grade d Ⅱ CT
