Note :

1. It is recommended that the return pipe is connected directly back to tank below the fluid level.

2. The specification chart to the right relates to performance achievable using HNC standard electronic controller type HNC-1085 and a pump flow of 2 lpm at oil temperature 45°C / 113°F and viscosity 45 cSt.

Position For Installation:

To install the pilot valve correctly mount with “bleed” up-wards in order to eliminate air and reduce the risk of air entrapment when used in conjunction with another main proportional valve.For a steady control pressure ensure that the pilot pressure pipe hoses does not exceed 30 cm.

Elimination Of Air(Air Vent) :

Set the pilot control pressure to 29.4bar(420PSI) and oper the bleed screw to eliminate the air.Lock the bleed screw when all air bubbles have been eliminated.

Manual Over-Ride:

It is possible to set the control pressure manually for commissioning and trouble shooting purposes.

Drain

Ensure that the return oil is piped back to tank directly and below the oil level.

EDG-01 Proportional Electro-Hydraulic Pilot Relief Valves General Information

[!–VMCatalog{div style=”margin-top: 30px;”}–]

1. Simplified piping system as result of using only  one remote electrically operated pilot relief valve for multiple functions requiring different pressure settings.
2. Step-less pressure control proportional to input current. 24V DC control and 0-10 volts reference single.
3. Good response with executer to reduce resonance.
4. Standard HNC electronic controller type HNC-1085 for best results.
5. Standard electrical connector to DIN 43650 (ISO4400).
