    Hydraulics problem

    Hi LittleInch You are 99% correct and thank you fr bearing with me to understand. The 1% is that its not driving a motor, its driving a reciprocating piston pump (dynaset 520 above) You are also exactly where i am with my thinking, a higher capacity pilot operated valve But the proportional...

    Hydraulics problem

    Hi R.Efendy Inlet can be up to 200 Lpm but the max out put of the NG6 has been tested an is 42 lpm We cannot change the valve gallery / manifold for a NG10 I feel like if i just knew the correct valve terminology my googling would give much better results. When i think a bout a spool valve...

    Hydraulics problem

    We did actually do a test to see what max flow we can get from the proportional valve , it was 42 Lpm fully open and we are looking for 85 :(

    Hydraulics problem

    Hi Ted We are stuck with the pressure as it is set by the HPU which is not manufactured or set by us, its is 200 Bar So we have to find a way of opening up more flow to our product Thanks !

    Hydraulics problem

    Yes the valve manifold is a flow And Yes , there are 6 solenoid valves and one proportional valve, the proportional valve was meant to have enough flow to drive our pump then the dynaset was introduced and we are very much stuck with the NG6 proportional valve (it lives in a pressure...

    Hydraulics problem

    Hi Akkaman I apologize for my lack of hydraulics background and appreciate your patience So the equipment that we supply will have a pressure and tank supply from a host piece of kit (a triton xlx) which is in effect a subsea HPU. This pressure and tank is fed into out valve pack (solenoid...

    Hydraulics problem

    Hi ted Good points and i apologize for not having these details in the post The output will drive a reciprocating piston pump (dynaset 520 which is more commonly used as a pressure washer) We are using the pump to perform pressure tests so it is beneficial to drive the reciprocating pump at...

    Hydraulics problem

    Hello all, i have a problem i hope you can help me with ... My hydraulics is basic at best and have been asked how we can control a 0-80 lpm pump when we only have the output of a NG6 proportional valve (0-40 lpm) valve to do it We have access to system pressure (200 Bar/150 Lpm max) so what i...
