进口气动凸耳式蝶阀德国洛克品牌厂家强烈推荐

进口气动凸耳式蝶阀结构特点：

1.体积小、重量轻、操作轻巧、便于安装。

2.由扭矩产生弹性密封。

3.三向偏心的独特设计使密封面之间无摩擦传动，延长了阀门使用寿命。

4.巧妙的楔形设计使阀门有越关越紧的自动密封功能，密封面之间具有补偿性、零泄漏。

5.更换零件材质可适用于各种介质，并可进行衬里防腐（衬F46、GXPP、PO等）。

6.凸耳式蝶阀可根据用户要求配置气动、电动装置，满足遥控和程控的需要。

7.蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°-90°之间，旋转到90°时，阀门则呈全开状态。

气动定位开关：根据气压信号（标准0.02-0.1MPa）的大小对阀门的介质流量调节控制。

电气转换器：将电流信号转换成气压信号，与气动定位开关配套使用（可提供防爆型）。

Parameters of imported pneumatic lug butterfly valve actuator:
Double acting actuator: two position control of valve opening and closing.
Single acting actuator (spring return): automatically close the valve in case of circuit or gas control failure.
Dual electric control solenoid valve: when one coil is powered on, the valve opens, and when the other coil is powered on, the valve closes. It has memory function (explosion proof type is available).
Single electric control solenoid valve: open or close the valve when power supply, close or open the valve when power off (explosion proof type can be provided).
Limit switch feedback device: remote transmission of valve open or close position signal (explosion proof type can be provided).
Electric positioning switch: according to the current signal (4-20mA), it can adjust and control the medium flow of the valve (explosion-proof type can be provided).
Pneumatic positioning switch: according to the air pressure signal (standard 0.02-0.1mpa), it can adjust and control the medium flow of the valve.
Electrical converter: convert current signal into air pressure signal, and use with pneumatic positioning switch (explosion-proof type can be provided).
