ZPD series electrical and gas valve locator | |
 | QZD2000 The function of the electric-gas converter is to convert the electrical signal output by the regulator into a gas signal. ZPD2000 Series electric-gas valve positioning and the valve use, the regulator output electrical signal, into the drive valve gas signal, can overcome the packing function and valve stem friction and medium pressure difference of the valve core imbalance force, improve the valve action speed, so as to ensure that the regulator according to the regulator correct output signal positioning. |
