Note :
1. Pipe the return direct back to tank on its own below the oil level for minimum back pressure.
2. The specification chart above relates to performance achievable using HNC standard electronic controller type HNC-4075, HNC-1085 and a pump flow of 125lpm (EFBG-03), 250lpm (EFBG-06), 500lpm (EFBG-10) at oil temperature 45°C / 113°F and viscosity 45 cSt.

Position For Installation:
To install the valve correctly mount with “bleed” up-wards in order to eliminate air and reduce the risk of air entrapment.
Elimination Of Air(Air Vent)
Set the pilot control pressure to 29.4bar(420PSI) and open the bleed screw to eliminate the air.Lock the bleed screw when all air bubbles have been eliminated.The above will ensure a stable adjustable pressure control and a smooth adjustable speed control.
Manual Over-Ride
It is possible to set the both control pressure control and flow control manually for commissioning and trouble shooting purposes.
Drain
Pipe the return back to tank below the oil level.lt is essential that the back pressure is kept to a minimum and does not exceed 2 bar(29PSI).
