Structural features of wafer butterfly valve:

1、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；

1. The unique design of three-way eccentricity makes no friction transmission between sealing surfaces, extending the service life of the valve;

2、由扭矩产生弹性密封；

2. Elastic seal generated by torque;

3、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；

3. The ingenious wedge-shaped design makes the valve have the function of automatic sealing, and the sealing surfaces have compensation and zero leakage;

4、体积小、重量轻、操作轻巧、便于安装；

4. Small size, light weight, light operation and easy installation;

5、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；

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control;

6、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. The material of the replaced parts can be applied to various media, and the lining can be anticorrosive (lining F46, gxpp, Po, etc.);

7、连续结构多样化：对夹、法兰、对焊；

7. Continuous structure diversification: butt clamp, flange, butt welding;

法兰式硬密封蝶阀特点：

Features of flange type hard seal butterfly valve:

1、蝶板密封圈为软硬层迭式金属片，具有金属硬密封和弹性密封的双重优点，无论在低温和高温的情况下，均具有优良的密封性能；

1. The butterfly plate seal ring is a soft and hard laminated metal sheet, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance at both low and high temperatures;

2、采用三维偏心结构，阀座与蝶板几乎无摩擦，具有越关越紧的密封功能；

2. The three-dimensional eccentric structure is adopted, and the valve seat and butterfly plate have almost no friction, with the sealing function of tighter and tighter closing;

3、阀体密封面，采用堆焊不锈钢、钴基硬质合金，密封面耐磨损，使用寿命长；

3. The sealing surface of the valve body is overlaid with stainless steel and cobalt based cemented carbide. The sealing surface is wear-resistant and has a long service life;

4、结构独特，操作灵活、省力、方便、不受介质压力的高、低影响，密封性能可靠；

4. Unique structure, flexible operation, labor-saving, convenient, not affected by high and low medium pressure, reliable sealing performance;
