interapp电动法兰蝶阀是工业管道中应用最为常用的阀门品种之一。蝶阀体积小、用料少、重量轻、口径越大相对其他阀更经济实惠。电动执行器旋转90°慢开式，操作简单。同时该阀门具有良好的流体控制特性。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，当开启度在大约15°至70°之间时，又能进行灵敏的流量控制，因此大口径的流量调节，蝶阀具有较大的优势。不适用于有颗粒和温度偏高的工艺介质中。
结构特点：
■阀板上下中孔处，采用球型摩擦面设计，扭矩更小，密封性更好
■阀座无靠背设计，扭矩更轻，也方便用户自行更换阀座
■法兰对夹孔连接适用多种标准

■密封阀座水线条设计，阀板密封面平面设计，彻底避免气动阀因长时间不开而造成的卡位现象

interapp electric flanged butterfly valve is one of the most commonly used valve types in industrial pipelines. Butterfly valve is small, less material, light weight, larger caliber relative to other valves more affordable. Electric actuator rotated 90 ° slowly open, easy to operate. At the same time the valve has good fluid control features. When the butterfly valve is in its fully open position, the thickness of the disc is the only resistance to the flow of the medium through the valve body, so the pressure drop across the valve is small and can be carried out when the opening degree is between about 15 ° and 70 ° Sensitive flow control, so large-caliber flow regulation, butterfly valve has a greater advantage. Not suitable for particles and high temperature process medium.
Structural features:
■ Valve plate up and down at the hole, the use of spherical friction surface design, smaller torque, better sealing
■ Seat without back design, lighter torque, but also to facilitate the user to replace the valve seat
■ Flange hole clamp connection for a variety of standards
■ seal valve seat water line design, valve seal surface design, completely avoid the pneumatic valve for a long time not open the card bit phenomenon
