Servo Valve

Servo valve can make precision flow control using low current and are suitable for electro hydraulic position, speed, pressure or force control systems with high dynamic response requirements.

NF series servo valves are result of more than 20years experience in the research, development, manufacture and application electro hydraulic control valves and systems. Our products are specially designed for hydraulic systems with various flow requirements such as turret controls for combat vehicle and motion controls for military tracked vehicle.
High performance electro hydraulic servo valves are suited for a variety of hydraulic control applications in commercial and defense industries. NF Servo valves are meet or exceed SAE ARP 490.
