品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……(比例积分)进口电动调节蝶阀输入控制信号（4~20mA或1-5V、0-10V）及单向电源即可控制运转，电动蝶阀特别是适合于介质粘稠、含颗粒、纤维性质的场合retz (Proportional integral) imported electric regulating butterfly valves can control operation by inputting control signals (4-20mA, 1-5V, 0-10V) and one-way power supply. Electric butterfly valves are especially suitable for situations with viscous media, particles, and fiber properties
进口比例积分电动调节蝶阀技术参数 Technical paramete
电动调节蝶阀又称比例积分电动蝶阀，通过4-20mA或者1-5V、0-10V点信号来控制阀门，即阀的开度与控制流体成比例，或者叫百分比 RETZ Electric regulating butterfly valve, also known as proportional integral electric butterfly valve, controls the valve through 4-20mA or 1-5V, 0-10V point signals, that is, the valve opening is proportional to the control fluid, or percentage
是由智能型电动执行器及蝶阀阀体组成，根据输入输出4-20mA信号控制 It is composed of intelligent electric actuator and butterfly valve body. It is controlled according to input and output 4-20mA signals
阀体流通能力大，对常温、干净介质。可选用阀板加软密封(橡胶圈、四氟圈)来减少泄漏(可达零泄露) The valve body has large circulation capacity and is suitable for normal temperature and clean medium. Valve plate and soft seal (rubber ring and tetrafluoro ring) can be selected to reduce leakage (up to zero leakage)
进口比例积分电动调节蝶阀性能特点∶ Performance characteristics
流体阻力小: 流线型蝶板设计，使流体阻力损失小，蝶板的厚度是介质流经阀体时候的阻力 Small fluid resistance: streamlined butterfly plate design makes the fluid resistance loss small. The thickness of the butterfly plate is the only resistance when the medium flows through the valve body
密封圈:橡胶密封圈即可位于阀体上，也可以位于蝶板上，可适用不同特点的介质，供用户选择 Sealing ring: the rubber sealing ring can be located on the valve body or on the butterfly plate. It can be applied to different media for users to choose
中线结构:采用中线结构，具有越关越紧的密封功能，密封性能可靠 Central line structure: the central line structure is adopted, with the sealing function of getting tighter and tighter, and the sealing performance is reliable
烤漆阀板：整体烤漆、能有效地防止锈蚀且只要更换密封阀座密封材料，就可使用于不同介质 Baking paint valve plate: the whole baking paint can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is changed
密封性可靠：密封件可更换，密封性能可靠，可以达到零泄露，并且实现双向密封 Reliable sealing: replaceable seals, reliable sealing performance, zero leakage and bidirectional sealing
安装方便：具有双向密封功能，安装时不受介质流向的控制，也不受空间位置的影响，可在任何方向安装 Convenient installation: it has two-way sealing function. It is not controlled by the flow direction of the medium and is not affected by the space position. It can be installed in any direction
