New! Tensor1 MWD Solenoir Rebuild and Replacement Program

Welbor's solenoid actuators are specifically designed for downhole and subsea applications.  Solenoids are customized for your design envelope, and provide the best force and stroke distance for a given geometry.  Whether a new design or a drop-in replacement for an existing system, we build solenoids with highest reliability and efficiency. Some reasons why you should consider Welbor for your downhole or subsea actuators:

Our extensive experience with exotic magnetic materials helps us select the best alloys for your design requirements.  An alloy's magnetic properties, machining properties, heat treat options, yield strengths, weldability, plating options, and expansion and friction coefficients are all part of the design considerations for a downhole or subsea actuator design.

Welbor uses proprietary epoxy compounds and a vacuum pressure impregnation technique for stabilizing and protecting wound assemblies.  The cure schedule and expansion properties prevent cracking, and the epoxy's temperature characteristics provide support while accommodating the thermal expansion of the wire.  The wound assembly can be potted into the solenoid or the bobbin can be replaceable.  The epoxy can be machined after cure to fit at assembly level. 

Our magnetic modeling capability allows us to quickly evaluate the feasibility of a specific design and predict the performance of the end product.

Welbor solenoid drive electronics increase the solenoid force available from a given battery voltage and current.
