Lohse type CAW

Product information

Lohse knife gate valve type CAW is a stainless steel gate valve with a straight valve plate that is fitted with a sealing surface on both sides, thus realising two-sided tightness. The compact design features plastic slide cups that minimise internal spaces and the required tightening torque.  

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).
