This kind of valve works on the principle of change of magnetorheological (MR) fluid properties in dependency on magnetic field intensity. The main advantages of such valves are simple construction and no moving parts. Probably the biggest weakness of current MR valves is too long time response of characteristic change on the control signal. That means that MR valve is not able to change its damping characteristics faster than in the range of tens of milliseconds.

This main weakness was eliminated by our innovative patented mechanical design. Progressive mechanical design together with patented MR controller principle ensures significantly reduced time response shorter than time response of any available MR valve. In comparison with common current controllers, the MR controller decreases the time response of MR devices while keeping high level of efficiency, small current ripple, design simplicity and low price.

The valve with current controller promises wide range of application, especially in cases when real-time damping characteristics changes are needed.

Main advantages

• Very short time response of characteristics change on control signal
• Mechanical design simplicity
• Low power demands
