Type Description
The bellow control valve is a pneumatically operated process valve with a single-acting diaphragm actuator. A PTFE bellow ensures the separation between medium and actuator. The materials used and the design of the media space allow the use under hygienic or aggressive conditions. It has a good cleanability. The combination with a controller (Type 869x) and the control cone integrated into the bellow enable the valve to handle demanding control tasks. The space-saving actuator with low internal volume not only results in a very compact size but also in remarkably low response times. The valve is characterized by a good control performance due to the low-friction design and has a linear characteristic. A certain variety of body and block system solutions are deliverable.
1）For neutral and aggressive media
2）Media separation by PTFE bellow
3）Hygienic design
類型描述
波紋管式調(diào)節(jié)閥是一款氣動(dòng)操作的過程閥門，配有單動(dòng)式膜片驅(qū)動(dòng)器。PTFE 波紋管可保障介質(zhì)和驅(qū)動(dòng)器安全分離。所使用的材料和介質(zhì)室的設(shè)計(jì)允許其在醫(yī)療衛(wèi)生環(huán)境或腐蝕性環(huán)境中使用。可輕松方便地清潔調(diào)節(jié)閥。通過與調(diào)節(jié)器（型號(hào) 869x）組合和集成于波紋管中的調(diào)節(jié)輪廓，可完成高要求的調(diào)節(jié)任務(wù)。驅(qū)動(dòng)器內(nèi)部容量小，非常節(jié)約空間，這不僅使得其結(jié)構(gòu)極為緊湊，同時(shí)也可大幅度縮短反應(yīng)時(shí)間。因無(wú)摩擦的結(jié)構(gòu)，閥門具有良好的調(diào)節(jié)性能及直線型特征曲線。另有多種殼體和區(qū)塊解決方案可供選擇。
（1）適用于中性和腐蝕性介質(zhì)
（2）通過 PTFE 波紋管分離介質(zhì)
（3）醫(yī)療衛(wèi)生設(shè)計(jì)
