本蝶閥采用與閥體相同材料加工成密封圈,采用電動(dòng)或氣動(dòng)傳動(dòng)。其適用溫度隨閥體選材料而定,公稱壓力≤0.6MPa,一般適用于工業(yè)、冶金、環(huán)保等管道作通風(fēng)調(diào)節(jié)介質(zhì)流量之用。其主要特點(diǎn)為:
1、設(shè)計(jì)新穎、合理、結(jié)構(gòu),重量輕,啟閉迅速。
2、力矩小,操作方便,省力靈巧。
3、采用適應(yīng)的材料以滿足低、中、高不同介質(zhì)溫度其及腐蝕性介質(zhì)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.
