Description
motorized valves,electric pneumatic valve,electronic valve,electric linear actuator valves   j. ZDL SERIES CONTROL VALVES ZDL electric control valve It receives DC signals from regulating instrument and adjusts the flow capacity medium directly, to keep technical parameters steady. The product has a number of advantages such as simple and exquisite structure, light weight, new and original design and large valve capacity. Compared with pneumatic control valve, electric control valve are more sensitive, convenient access to energy, rapid transmitting and long signal distance etc., therefore be applied to the fields of petroleum, chemical plant, power plant, metallurgy, paper making, pharmacy etc. Main technical parameters: nominal size: DN15-300mm (1/2"~12) nominal pressure: PN(MPa)1.6\4.0\6.4(ASME Class 150/300/400) leakage class: IV/ V signal range:4-20Ma characteristics: quick open temperature range: -196~+560celsius   Types of ZDL SERIES: ZDLP electric single-seated control valve, the inherent rangeability50:1; pressure recovery coefficient: flow to open: 0.92; flow to close:0.85. It can categorize into standard type, heat dispersing type, and low/high temperature type. ZDLM electric cage control valve, the inherent rangeability50:1; pressure recovery coefficient: 0.84. It can categorize into standard type, heat dispersing type, and low/high temperature type.   ZDLQ(X) electric confluence/shunting control valve, the inherent rangeability30:1; the medium temperature controlled below 200celsius(confluence type). It can categorize into standard type, heat dispersing type, and low/high temperature type.   ZDLN double-seated control valve, the inherent rangeability50:1; It can categorize into standard type, heat dispersing type, and low/high temperature type.
