阀门如何翻译？ samson 阀门，cavity-free valve，用于食品工业 control valves designed for aseptic applications in the food processing industry, often just called food or aseptic valves, feature a cavity-free body design that eliminates potential bacteria growth areas. polished stainless steel parts are used for aseptic valves, such as samson's type 3347 valve, to ensure the highest purity level of the process medium. a special ptfe bushing and an additional steam line connection that is used to meet very stringent purity requirements prevent bacteria from spreading at the actuator stem guide. samson's type 3249 valve is equipped with an epdm diaphragm and a backup safety packing box to ensure total protection against bacteria spreading and product leakage. these sealing systems constitute the main components of the valve construction, they have been thoroughly developed and designed to ensure a long service life. normally, angle valves are used as aseptic valves because they are self-draining and can be cleaned (cip) or sterilized (sip) without being disassembled. type 3345 valves feature a diaphragm made of rubber, nitrile, butyl or ptfe that acts both as a seal and a valve plug. the cavity-free valve body is therefore ideally suited to pasty, fibrous, highly viscous products. and it may be lined with rubber or ptfe. these valves can be easily installed into the pipeline because they are available with various connections including hygienic couplings, flanges and clamp connections according to iso 2852 and welding ends. the design and the materials of the aseptic valves meet the stringent fda requirements. furthermore, samson's complete manufacturing process is subject to a quality assurance system certified to iso 9001.查看更多
