A resistor assembly for a motor drive circuit for an electric motor assembly can have a generally circular shape. The resistor assembly includes a resistor with input and output connectors and a pair of conductor elements extending from the input and output connectors. The pair of conductor elements extend adjacent each other along a curved serpentine path so the resistor has a generally circular outer perimeter and a generally circular inner perimeter. The curved serpentine path of the pair of conductor elements allows current to flow through the pair of conductor elements so that magnetic fields generated by the current flow through the pair of conductor elements cancel each other, thereby providing the resistor with low inductance.

Technologies are described for dual motion shutoff valve assemblies. In various examples, valve assemblies include a sequencing drive mechanism and an eccentric shaft mechanism operable to linearly retract the valve disk from a gasket surface to effectively reduce scratching and friction of the gasket surface during valve opening and closing operations. In some examples, the sequencing drive may include two interlocking concentric driver rings, a retaining housing, and roller lock pins. Three guided pins of the sequencing drive may be configured to prevent the valve from rotating, while also causing the valve to retract linearly from the gasket surface via the eccentric shaft. Following retraction, an inner driver of the sequencing drive may allow the roller lock pins to move and lock the outer driver, which in turn may lock the valve disk to the shaft and rotate along with the shaft, which may be a single or dual shaft.

Technologies are generally described for valve assemblies that include a valve body whose inner wall defines two ports and a controllable flow path that extends along the inner wall between the two ports of the valve body. Each port may be fitted with a corresponding gasket. A rotatable member disposed in the controllable flow path of the valve body may include a hemispherical-shaped body with a substantially flat disk-shaped surface portion, and a seal ridge formed about a perimeter of the substantially flat disk-shaped surface portion. During opening and closing operation, the seal ridge may be selectively engaged with either one of the gaskets reducing an initial contact surface, and thereby reducing friction between the rotatable member and the gaskets.
