JCB excavator hydraulic problems. Pressure reducing valve on LS. I've looking at the schematics for LS pumps and controls. Typically, flow is controlled by a large variable valve with the LS signal to the pump after the valve. This subjects the entire flow to the pressure drop through the valve. Not a problem with low flow, but as the

Pump with Pressure-Reducing Valve and Two Loads. This example shows a typical power unit consisting of a fixed-displacement pump driven by an angular velocity source, a pressure-relief valve, a pressure-reducing valve, and two variable orifices. The variable orifices simulate fluid consumption in the main system and in the reduced pressure branch.

Mar 09, 2016 · It's basically pilot pressure to run the pilot control systems, joy sticks, solenoid valves and some of the main pump functions. Plug a gauge into the pilot system and you can see what is there. This is usually a steady pressure but may drop a little when the engine is at low idle. There will be a minimum pressure spec in the book.

A pressure-reducing valve is normally an open, 2-way valve that allows system pressure fluid to flow through it until a set pressure is reached downstream. It then shifts to throttle flow into the branch. The forces exerted by pressure downstream actuates a pressure-reducing valve. A pressure drop across the valve's spring-based main spool is
