P377.U001a General user manual for P377 & P447 - An insufficient deburring and/or a too rough surface (>Ra0.8) of the cavity may damage the o'ring during the assembly process and thus, create internal or external leaks. - Please refer to the footprint on your catalog drawing The visual control of the cleanliness and the state of the o'ring before assembly greatly reduces the risk of external leakage. Exert a movement of combined pressure and oscillating rotation on the body of the valve, to ease the introduction of the o'ring whilst under radial compression. The aim is to create a dynamic movement...

P377.U001a General user manual for P377 & P447 No specific tool is needed. - The M3x6mm screws are only used to maintain the valve is in its cavity and in no case to ease or help in its introduction. The tightening of the screws must only be carried out after the complete introduction of the valve into its cavity. - The use of a hammer or other object to introduce the valve axially by force should be strictly avoided. A screwdriver or Allen key is required for subbase screws. A 15 mm open-end spanner is required for final screwing of the M5 body. 6. Fluid filtering The stroke or the movement...

P377.U001a General user manual for P377 & P447 - If there is a risk that the fluid may flow back on itself, it is also advisable to place a filter downstream of the valve. - The active surface of the filter must be fixed in such a way that pressure decay is kept to a minimum. - Otherwise, the filter will limit the flow and the valve will not be able to meet the flow specifications given. The electrical signal may be one of 3 types : In a coil the electromagnetic force is directly proportional to the current passing through it. The current drive is therefore, the most favorable method because...

P377.U001a General user manual for P377 & P447 - Nominal current - Nominal resistance - Maximum pressure - Serial Number 10. Standard Trouble shooting - Check the power supply (voltage/current limit). - Check the connector (good insertion). - Check the wire (not damaged). - Inlet partially obstructed Check if there are no particles in the inlet. - Outlet partially obstructed Check if there are no particles in the outlet. - Courant insufficient Check the power supply (voltage/current limit). - Check assembly to the manifold. - Check the tightening torque of the screw. - Check cleanliness of the...
