品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……进口电动对夹式蝶阀电动执行器采用一体化结构，接入220VAC电源即可控制运转，也可加入控制模块,输入控制信号（4-20mADC或1-5VDC）进行调节控制

retz The imported electric neutral soft sealing butterfly valve (clamp, flange) adopts an integrated structure, and the electric actuator can be controlled to operate by connecting to a 220VAC power supply. Control modules can also be added to input control signals (4-20mADC or 1-5VDC) for adjustment and control

功能介绍 Function introduction

进口电动对夹式蝶阀采用中线弹性橡胶密封，弹性阀座配高精度蝶板确保零泄漏，阀杆底、中、上部配有衬套，用于支撑和旋转滑动，保特最小磨擦力 The imported electric center line soft seal butterfly valve (wafer, flange) adopts the center line elastic rubber seal, the elastic valve seat is equipped with high-precision butterfly plate to ensure zero leakage, and the bottom, middle and upper parts of the valve rod are equipped with bushings for support and rotary sliding, and the minimum friction force is guaranteed

进口电动对夹式蝶阀设计特色 Design features

1、蝶板的回转中心(即阀杆的中心)位于阀体的中心线和蝶板的密封面截面上 The rotating center of the butterfly plate (i.e. the center of the valve stem) is located on the center line of the valve body and the section of the sealing surface of the butterfly plate

2、小巧轻便，容易拆装及维修，操作扭矩小，90°回转开启迅速，并可在任意位置安装 Small and light, easy to disassemble and repair, small operating torque, 90 ° rotation and quick opening, and can be installed at any POSTTTION

3、流量特性趋直线，调节性能好。蝶板与阀杆的连接采用无销钉结构，克服了有可能的内泄漏点 The flow characteristics tend to be straight, and the regulation performance is good. The connection between the butterfly plate and the valve rod adopts a pinless structure, which overcomes possible internal leakage points

4、蝶板外圆采用球面造型，提高了密封性能及延长了阀门的使用寿命，带压启闭5万次以上仍保持零泄漏 The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve, and keeps zero leakage after opening and closing under pressure for more than 50000 times

5、密封件可更换，且密封可靠达到双向密封 The sealing element can be replaced, and the sealing is reliable to achieve two-way sealing

6、蝶板可根据用户要求喷涂覆层，如尼龙或聚四氟类 The butterfly plate can be coated according to user requirements, such as nylon or PTFE

7、可设计成法兰连接和对夹连接 Can be designed as flange connection and wafer connection
