Ledeen Actuators

The Ledeen product range stems from the employment of Fluid Power, in the form of high pressure hydraulics, as the final power element. The high pressure hydraulic fluid is generated by any available prime power source, be it pipeline gas, local instrument or plant air; the local electricity supply or from a central hydraulic system.

The Ledeen product range also includes spring return actuators which can be powered by any of the prime power sources previously mentioned i.e. direct pneumatic, pneumatic/hydraulic, electro/hydraulic etc. Ledeen actuators are based upon modular construction where an optimum number of basic frame units can be equipped with any combination of hydraulic cylinder, direct pneumatic cylinder, spring return capsule any power pack operating from air, electricity, or fluid power and include stored energy.
