Lohse gate valve type CAW

Lohse gate valve type CAW

The Lohse 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. In doing so, it realizes bi-directional tightness. The compact design features polymer slide cups that minimise internal spaces as well as required tightening torque.

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