What hydraustar does

Hydraustar is a privately held French industrial SME (PME) founded in 1994 and headquartered in Saint-Firmin-des-Prés (Loir-et-Cher), France, specializing in the design, manufacture, repair, and maintenance of hydraulic servo-valves, servo-distributors, and servo-cylinders. The company serves industrial clients across aerospace, defense, automotive, steel/metals, energy, railway, and simulation sectors, with named enterprise customers including AIRBUS, SpaceX (Falcon 9 thrust vector control), Blue Origin, SAFRAN, THALES, and Arcelor Mittal. The company originated from a partnership with a UK sister entity established in 1984 by the same founder — a former Dowty Hydraulics engineer who leveraged a Moog European manufacturing license to build an independent multi-brand servo-hydraulic repair and manufacturing operation.

The company's core technology centers on proprietary use of titanium and sapphire materials ("Saphir technology") in servo-valve construction, which the company states delivers 5-10x service life versus competing products, a near-zero return rate of 0.1 per 100 units, and 10x extension of internal-feedback service life through a rotating cartridge design. The product portfolio spans over 20 servovalve series (Séries 200, 300, 45X, 46X, 55X, 55X.E, 50X, 50X.E, 59X, 65X, 750, 850, 89X, 89X-2, 89X.E, 901HF, 902HF, 990, 1100, 155X) plus the F40 servodistributeur, covering flow rates from 1 to 1,000 l/min and pressures from 15 to 500 bar, with standard, high-frequency, and integrated-electronics variants. Products carry ATEX/IECEx certifications for explosive environments and ISO 10770-1:2009 testing compliance, and the company holds ISO 9001 quality certification. A complementary electronics line includes amplifier modules, control cards, control boxes, and portable testers, alongside hydraulic accessories (adaptation blocks, sandwich protections, measurement blocks, pipe-mounting bases, flushing/closing plates).

Hydraustar generates revenue through two intertwined streams: (1) sale of proprietary servovalves, servodistributors, servocylinders, electronic modules, and accessories into OEM, replacement, and obsolescence-management markets; and (2) repair, maintenance, replacement, exchange, loaner, and rental services across 50+ servo-valve brands. Pricing is quote-based with 30-day offer validity, a 30% deposit required on orders exceeding €15,000, net-30 invoicing, and warranty terms of 1 year on new products and 6 months on repairs (extendable to 3 years with documented fluid cleanliness). The go-to-market is direct sales to enterprise industrial buyers with no disclosed reseller or distribution channel.

Partnerships

Three partnerships are on record, tiered core and minor.

• MoogcoreTechnology or Integration · 1 January 1984Moog granted Hydraustar's UK sister company a license for servo-valve manufacturing for Europe in 1984. Moog provided unrestricted spare parts for maintenance and repair before the entity became independent. The partnership established Hydraustar's foundations and technical expertise in servo-hydraulic distribution, with Moog continuing to support the entity during its growth phase.
• UK Sister CompanycoreStrategic or Co-development PartnerA sister company was created 10 years before Hydraustar (in 1984) in the UK in response to similar demand for independent servo-valve repair identified by its creator while working at Dowty Hydraulics. The UK entity was supported by Moog and served as the model for Hydraustar's establishment in France.
• Dowty HydraulicsminorOthersDowty Hydraulics held a license for servo-valve manufacturing for Europe granted by Moog. The founder of Hydraustar's sister company worked for Dowty Hydraulics, which identified the market opportunity for independent servo-valve repair services.
