LL spherical reversing valve


Sanitary Stop/Reversing Valve


The series of valve are major let the medium reach the purpose of reversing or end stop, because the good sealabilityand cleanability,they are extensively use to different sanitary industry areas.

Standard design

Various standards of valves can be provided to clients:DIN,3A,SMS,ISO/IDF,BS/RJT,ASME/BPE etc.

The series of valve have two types valve,that is the cut-off type and reversing type,the cut-off type can made of two or three pipeline connector, the reversing valve can made of three to five pipeline connector, their variety fully satisfied theneeded of market

Working principle

The series of pneumatic cut-off reversing valve change the energy which process by compressed air to the mechanical energy, the mechanical energy can drive the valve rod axial moving, thus move the different location of Seal elements,which can control the switch for inlet of pipeline,finally realise the purpose of medium reversing or stop.

The manual cut-off reversing valve series control by handle, also reach the purpose of medium reversing or stop at the end.


·Steel parts:stainless steel 304,stainless steel 316L

·Seal: PTFE,O type seal ring

·Up diaphragm: NBR diaphragm and standard diaphragm

·Down diaphragm: PTFE,EPDM and standard diaphragm

·0 type ring:NBR diaphragm and standard diaphragm.

(Remark: when the temperature beyond 95 degree,the diaphragm need choose PTFE,O type ring choose EPDM.)
