Product Introduction
产品结构特点 Construction features
本蝶阀采用与阀体相同材料加工成密封圈，采用电动或气动传动。其适用温度随阀体选材料而定，公称压力≤0.6MPa，一般适用于工业、冶金、环保等管道作通风调节介质流量之用。其主要特点为：
1、设计新颖、合理、结构独特，重量轻，启闭迅速。
2、力矩小，操作方便，省力灵巧。
3、采用适应的材料以满足低、中、高不同介质温度其及腐蚀性介质等。
This butterfly valve is made of the same material as the valve body to be machined into a sealing ring with electric or pneumatic transmission. The applicable temperature is determined according to the body selection material, and the nominal pressure is not equal to 0.6mpa, which is generally applicable to the ventilation regulating medium flow in industry, metallurgy, environmental protection and other pipelines. Its main features are:
1. The design is novel, reasonable, unique structure, light weight and fast.
2. Small torque, convenient operation and convenient operation.
3. Adapt the materials to meet the low, medium and high temperature and corrosive media.
