TLX Technologies has developed a discrete proportional pilot valve which provides precise control at up to four specific programmed discrete positions. This capability is beneficial for various applications such as electric vehicle cooling systems.
The valve requires zero-steady state power, has zero hysteresis by design, features a low-pressure drop and and only needs +/-12V for flow change. This valve is intended for high-flow applications and is scalable to application requirements. This design is patent-pending.
