Cast aluminum manual Manual Powder Powder butterfly valve spool valve is composed of two, in the middle of a valve plate, which has an intermediate ring, valve plate has a splined shaft, spline shaft has a head for connecting the cylinder (pneumatic actuators) Scope: concrete mixing stations and dry powder. Aluminum powder manually butterfly Synonyms: Powder butterfly Connection: Flange material: cast aluminum, nominal diameter: 100-350 (mm), the driving medium: compressed air pressure range: 0.2Mpa, suitable temperature : maximum 80 ℃, the main material: half body is aluminum alloy rotary valve wear-resistant polymer material, the structure forms: vertical plate, transmission forms: pneumatic and sealing form: soft sealing type, pneumatic actuator configuration: CP101, CP126 model. Industrial design with the use of a special composite material to make the butterfly valve has a compact and lightweight structure, miserable plate wear, long seal life, easy installation and maintenance, etc., is a cost - highly effective powder valve. Aluminum powder manual valve is closed parts (valve or disc) for the disc around the valve axis to achieve the opening and closing a valve in the main pipeline from the off and throttling. Butterfly is a disc-shaped opening and closing parts of the disc, in the valve body rotating around its own axis, so as to achieve the purpose of opening and closing or adjusting. Aluminum powder manual valve fully open to fully closed is typically less than 90 °, butterfly and butterfly stroke itself is not self-locking capability, in order to locate the disc, and to install the worm gear on the stem. Using worm reducer, not only can make the disc has a self-locking capability, so that the disc stopped at any position, but also to improve the operating performance of the valve. Industry-specific characteristics of butterfly valves to high temperature, higher pressure range, the valve nominal diameter large, carbon steel valve body, valve plate seal with a metal ring to replace the rubber ring. Large temperature valve welded steel plate manufacturing, mainly for duct smoke and gas pipelines hot medium.
