Table: Coil outer surface temperature range

Model Coil outer surface temperature When continuously energizing adjacent valves at t he same time, ambient temperature rises since the coil generates heat. Implement measures to exhaust PVQ10 excess heat so that the temperature remains within the range of the table on the PVQ30 proximal sect ion (approx. 1 mm) when t he right. maximum current is applied

Coil

Working Principle

Core

The armature is attracted to the core by electromagnetic force as the coil is energized. When the applied current varies, the attraction force also varies proportionally to it. The f low rat e is controlled by the movement (str oke) of the armature, depending on the balance between this attraction force and the spring load.

PVQ Series

P1 = No conditions, P2 = 0 MPa (Atmospheric pressure) In this case, all orifice sizes of PVQ30 series satisfy the required flow rate. (Flow rate when rated current is applied) The table below shows the pressure differentials to satisfy the required flow rate. In the flow rate characteristics charts, a pressure differential over the flow rate indicated by the dashed line (75 L/min.) up to the max. operating ARJ pressure differential will satisfy the required flow rate.
