Lohse type CBS

Product information

Lohse knife gate valve type CBS is a stainless steel gate valve with a knife valve plate that is fitted with a control plate in the upstream bore. The control plate can be fitted with a triangle or pentagon to achieve optimum control range. The compact design features plastic slide cups that minimise internal spaces and the required tightening torque. The CBS can be equipped with various actuator systems and be adapted to specific circumstances.   

All Lohse valves use the Lohse modular actuator system with a choice between manual actuation (handwheel, handwheel with rising stem, T-spanner, chain) and non-manual actuation (electric and pneumatic).
