Damcos LPU-D – Double-Acting Operated Actuator

The Damcos LPU-D – (Local Power Unit) comprehends an integrated electro-hydraulic system for remote control of valves and actuators and is especially developed to be bulkhead mounted or mounted directly on valve actuators, primarily onboard ships. The LPU-D version is used with double-acting actuators requiring hydraulic pressure for operation both for opening and closing the valve.

Damcos LPU-D Modules Overview

Damcos LPU-D Overview

The LPU-D is designed for the control of double-acting actuators requiring hydraulic pressure for operation in both opening and closing the valve. The LPU-D can be mounted either directly on actuator or remotely on bulkhead. In the modular design of the LPU the Base Hydraulic Block acts as the rack and the Control Block as the heart of the hydraulic function. For LPU-D these blocks are named Base Hydraulic Block D and Control Block D. The LPU standard versions comes with several electrical alternatives with different levels of possibilities and functions, such as LPU Basic, Plus, Elite and P-NET.
