Parker负载敏感阀培训L90LS

Arial lift Forest machine

Excavator

Backhoe loader

Hook loader Refuse collector Large wheel loader

n When partial pump flow is used for individual functions

n At high intensity usage

n To create simple system solutions when a number of functions with different flow rates is demanded n When system layout is spread out

n At simultanious operation of functions n Power control and energy conservation

n

Reduce energy losses at idling and transportation

Suitable when;

System with variable pump and LS

Save energy, design advises

n Avoid to mix light and heavy loads from the same pump.

n Avoid to mix large and small flow demands from the same fixed pump.

n Never control max flow with line mounted restrictors.

n Always use the pump regulator to set maximum work pressure when you are using a variable pump. The pressure limiter of the valve needs to be set at least 30 bars above.

n Avoid to limit valve work port pressure with the chock valves, use the build in individual work port feed reducer.

n Make sure that the cylinders are correctly connected to the

valve, the valve is normally adapted to the cylinder ratio.
