Lee Products has introduced a range of miniature high-flow solenoid valves with an innovative sealing arrangement that allows overall valve size to be reduced without compromising performance. The Lee MultiSeal dispenses with O-rings and back-up rings, and simplifies port layout by allowing two ports to be sealed on the same centreline. This in turn allows the hydraulic portion of the valve to be smaller, resulting in a compact, low-profile installation, which reduces the overall size of the manifold. During qualification testing the valve provided consistent performance over 2.5 million cycles.
