About This Product

■Features

・Nozzle flapper type two-stage electric/hydraulic servo valve. - Compatible with high power and high speed, with high controllability and followability. - Suitable for high-response, high-precision hydraulic control systems. - The ball group at the tip of the feedback pin is made of sapphire, which has a hardness second only to diamond. This head has passed 251,425,121 tests.

■Introduction examples (in no particular order, titles omitted)

・Rocket/Spaceship SpaceX (USA) ・Airbus (France) in the aerospace industry ・Aircraft Lufthansa (Germany) ・Railway vehicle Alstom (France) ・Volvo (Sweden), a manufacturer of trucks and construction equipment ・Tata Steel (India), an integrated steel manufacturing company ・Subsea 7 (British Cayman Islands)

■Failure diagnosis service

When a problem occurs in a hydraulic servo system, the first suspect is the servo valve. However, it is extremely difficult to conclude that the servo valve is the cause of the problem based on the system alone. In addition to our own valves, our experienced staff uses our own tester stands to diagnose the failures of valves from various manufacturers. If the item cannot be repaired, we will suggest an equivalent item. *Other product numbers are available.
