there are various electric regulator, small make up in before, have introduced, according to the customer's feedback, small make up to edit the electric regulator dn250 best-selling list, hope will be helpful to the user.

TOP1: adjust air conditioning heating steam flow VB7000 proportional integral electric two-way valve regulating valve DN250 fresh air units of the system is suitable for use in air conditioning systems in winter/summer temperature control. TE - by temperature sensors 1, the TC - pid temperature controller 1 and electric two-way valve of TV - 1 supply air temperature control system, installed on the air supply pipe to TE - 1 the temperature of the detected signals to TC - 1, will TE by TC - 1-1 of values compared with the set value constantly, constantly output signal at the same time, control TVTV - 1 opening continuously adjustable. Eventually keep TE - 1 measurement of temperature in setting temperature range. After the coil temperature is lower than a certain threshold, protection switch TS - at low temperature Send 1 cut off the power of the motor, so that fresh air valve closed, prevent water ice coil, coil up to crack. TOP2: D971X - 16 electric soft seal the wafer butterfly valve/valve/slowly open valve DN200DN250DN300 small size, less material, light weight, the larger the diameter is more economical than other valve. Pneumatic actuators rotate for 90 & deg; Quick opening and closing, simple to operate. At the same time, the valve has good flow control characteristics. Butterfly valve in the fully open position, the butterfly plate thickness is medium flows through the body when the only resistance, thus produced by the Industrial Valves pressure drop is small, when opening in about 15 & deg; & 70 deg; Between, and can carry on sensitive flow control, so the flow control of large caliber, butterfly valve has great advantage. Do not apply to the medium particles and high temperature process. Sealing seat water line design, valve plate seal face of the plane design, completely avoid pneumatic valve screens phenomenon caused by long time don't open hole in the valve plate up and down, the spherical surface of friction design, torque smaller, better sealing seat back design, torque and lighter, also convenient for the user to replace the seat of the flange hole connected to the clamp for a variety of standard TOP3: GID electric high vacuum butterfly valve cast steel valves, stainless steel DN250300350400 GID electric high vacuum butterfly valve is by electric device to drive the valve stem and valve plate to perform opening and closing action, reach the valve opening and closing to put through or cut off the airflow in the vacuum line. The suitable medium for pure air or non corrosive gas. With signal feedback device. This butterfly Industrial Valves is adopted the midline type disc plate and short structure is a new type of structure design and manufacture of the steel plate welding, compact structure, light weight, easy installation, small flow resistance, big circulation, avoid the influence of high temperature expansion, convenient operation. The body without connecting rod, bolts, etc. , reliable operation, long service life. Can be installed in a transfer, not affected by the medium flow direction. Compiling numerous customers for everybody finishing above for small domestic electric regulator dn250 best-selling list, that's the will of the small make up only, if wrong, also please understand, if you have the electric regulator dn250 aspects of demand, you can contact us, we will have a professional technical personnel to provide you with complete product solutions. , around you electric regulating valve manufacturing expert!
