Description:
The consists of an inlet manifold, which supplies water to a spear valve that allows users to vary the jet cross section while maintaining the water velocity. The runner itself is mounted in a clear acrylic enclosure to allow maximum visibility of the workings. The unit incorporates a pressure sensor to measure the inlet condition of the water. This pressure can be accurately controlled using the software supplied with the service unit.
