Special Linear Actuators
Double Acting, Single Acting
Up to 32” bore

Davis design and manufacture piston linear actuators and control systems for most of the major process valve manufacturers and distributors based both in the UK and throughout the world. We also supply to the major oil, chemical and civil engineering companies.

Linear Actuation requirements are generally specific to each valve/application, as even similar type/classes have individual thrust and stroke requirements, compounded by differing supply pressures.

To provide the ‘Best Cost Effective Solution’ we establish the operating criteria for the valve to be actuated, in terms of stroke, close force, opening force etc, and propose a tailored package to suit.

For more information please contact us.
