不同配置的不銹鋼外殼

許可 FDA、CE、USP V、USPRobolux multiway multiport diaphragm valve, pneumatically operated

This Multiway-Multiport Diaphragm Valve  system This Multiway-Multiport Diaphragm Valve system is designed for control of ultra pure, sterile,

 aseptic and steam/CIP ? uid paths. It enables optimal sampling, draining or diverting of critical process ? uids.

The valve range is based on the patented Robolux technology, where two seats are placed under one diaphragm.

并襯以各種耐腐蝕或耐磨材料、隔膜材料橡膠及聚四氟乙烯。

襯里的隔膜耐腐蝕性能強，適用于強酸、強堿等強腐蝕性介質的調節(jié)。

 This design eliminates dead legs and will minimize the ? ow system volume.

The valve body is machined from a single piece of bar stock stainless steel.

減小了安裝成本

Technical data Port connection size 1/4” to 2”, DN 4 - 50 Materials Valve body Diaphragm  Actuator 

? 1.4435 stainless steel (316L) ? EPDM, EPDM (AD), advanced PTFE/EPDM laminated (EK) 

? Stainless steel bodies in different configurations 

氣動隔膜閥的反饋信號采用無觸點傳感技術。

? ASME BPE / DIN 11866 series C ? DIN 32676 Series A (DIN Tube)

 The high quality diaphragms are available in several different USP class VI approved materials. The valve is operated with compressed air. 

? Reduced number of valves and welds 

提高了過程效率

All valves will be delivered with 3.1 certi? cate, installation drawing and manual instruction.

? Ra ≤ 0,5 μm (ASME BPE SF1) (external Ra ≤ 1,6 μm)

該產品采用薄膜式推進氣缸，替代活塞氣缸，

但是，由于隔膜和襯里材料的限制，

耐壓性、耐溫性較差，一般只適用于1.6MPa公稱壓力和150℃以下。

? Reduced installation costs 

?  Ra ≤ 0,38 μm (ASME BPE SF4 / DIN HE4) (external Ra ≤ 1,6 μm) (others on request) Medium pressure max. 8 bar1) 

(depending on actuator and diaphragm) Pilot pressure 6-10 bar for RV50/70 6-7 bar for RV110 Pilot air ports Thread G 1/8”

無泄漏，能用于高粘度及有懸浮顆粒介質的調節(jié)。

隔膜把介質與閥桿上腔隔離，所以沒有填料介質也不會外漏。

當氣源發(fā)生故障時，尚可操作手輪使閥門啟閉。

? DIN EN ISO 1127 / ISO 4200 / DIN 11866 series B 

? DIN 11850 Reihe 2 / DIN 11866 series A

隔膜把介質與閥桿上腔隔離，所以沒有填料介質也不會外漏。

隔膜閥的結構簡單、流體阻力小、流通能力較同規(guī)格的其他類型閥大；

? Approvals FDA, CE, USP VI, ATEX, 3.1The draining is achieved differently depending on the valve type. 

It is very important to fully understand the ? ow paths of each individual valve body before deciding which port/connection (marked with A, B, C 

or D) to select for draining. Consult with your Bürkert contact person if there are any questions. 

隔膜閥的流量特性接近快開特性，在60%行程前近似為線性,60%后的流量變化不大。

氣動形式的隔膜閥尚可附裝反饋信號、限位器

及定位器等裝置，以適應自控、程控或調節(jié)流量的需要。

 Temperature EPDM (AD)  advanced PTFE/EPDM laminiert (EK) Ambience +5 to +130°C (steam sterilisation +140°C for 60 min) +5 to +90°C

? Allows optimized processes designs 

The examples below show how to get the optimum draining for the 3C2S/4C2S and 4C4S

隔膜閥用耐腐蝕襯里的閥體和耐腐蝕隔膜代替閥芯組件，利用隔膜的移動起調節(jié)作用。

隔膜閥的閥體材料采用鑄鐵、鑄鋼，或鑄造不銹鋼，
