subsea solenoids
Our staff has decades of experience designing and manufacturing products for oil field environments.
The Welbor team understands the importance of consistent, reliable performance of our products. They know that our customers depend on them to function in the most demanding environments, and that a failure can be extremely costly. Our culture revolves around shipping only products that are the best that we can make them.

- No Sliding Seals
- Welbor solenoids are structurally capable of
withstanding deep water hydrostatic pressures. This eliminates the moving
seals or bellows associated with pressure compensation.
- Deep Penetration Electron Beam
Welds
- Soft magnetic materials, which are necessary
for solenoid operation, are prone to corrosion and pitting. Welbor
solenoids� magnetic materials are joined using deep penetration
electron-beam welds to prevent corrosion-induced leaks commonly experienced
at o-ring seals or surface welds in soft magnetic materials.
- Encapsulated Coils
- Wire and insulation are subjected to magnetic
forces and expansion and contraction from temperature changes as the
solenoid's power is cycled. If the wire is free to move, it can be prone to
failure from stress and fatigue. Welbor's proprietary vacuum-pressure
impregnation process with our own epoxy formula eliminates voids in the coil
and housing and provides a combination of flexibility, strength and
stability. Numerically controlled coil winders ensure that coils are wound
with consistent tension and without the stress concentrations associated
with random winds.
- Quality
- Because we wind, encapsulate, assemble and
test Welbor solenoids in house, we are able to maintain the highest quality.
Welbor solenoids are pressure and leak tested at every critical stage of
construction. Each solenoid is individually tested at its normal operating
current for both actuation force and friction along the entire length of the
stroke.
- Response
- Welbor stocks a wide range of types and sizes
of magnetic materials, wire, and epoxy. Our modeling capability reduces
design cycle time, and proven construction techniques minimize risk on new
geometries. Welbor's response time for new applications is often less than
for other supplier's "off-the-shelf" products.
