CV2000LS – Post Compensated Valve
CV2000LS Post Pressure Compensated Flow Sharing Valve
– Pressure compensatedFor both fixed and variable pumps
– Post compensatedIf the flow consumption is larger than what the pump can supply, all sections will continue to work and all the functions will proportionally give out less flow. No function alone will take the whole flow and you can thereby avoid that the heaviest load slows down, or stops entirely.
Product advantages
Product advantages
– Inlet variable pump with emergency stop functionShuts down the flow into the valve and drains the valve internally so that no pressure will be built up
– Inlet fixed pump with electric unloadingSaves energy and avoids pressure to be built up in the valve
Product advantages
-Pressure limiterSets the maximum pressure individually on each port
- Port specific shock/anticavitation valve for each section modulePort specific shock valve for each section module which opens if there is a collision with exterior objects and quickly relieves the pressure and dumps the flow to tank
- Pressure limit for each sectionLimits the load pressure out on each section
- External control of the port pressureThe CU-port makes it possible to shut a function off in certain conditions. It is possible to shut down the flow from the specific port, or to control the outlet pressure proportionally. The advantage is that you can choose different fixed pressure adjustments
- Mechanical maximum flow limiterSets the maximum flow for each section
- Float Position optionDecouples the hydraulics from he loader and the machine follows the profile of the ground
Product advantages
-High Pressure Carry OverUsed for serial connection of a number of valves to one pump. Important function when you want to prioritize a certain valve
- Parallel connect bypass valves (fixed pump)For parallel connection of a number of valves to the same pump. All valves function as post compensated which makes it possible to prioritize a certain valve
- Easy to convert to hydraulic controlEasy to convert from electronic to hydraulic control. All that needs to be done is to exchange the solenoid valve for an adaptor

“From the beginning we choose Nimco as a supplier because of the price but also due to the performance. The
product is quite unique, especially CV691, the performance is superb and it is extremely beneficial. We have a lot of
contact with the engineers at Nimco which are all very competent in the products. I experience that the service is
very efficient. We get the support we need very quickly. Our company has benefited a lot from working with Nimco.
The valve 691 and 791 makes the machine compact and tidy and it saves a lot of space. The valves make the machine
10% more efficient than with competitor’s products. We have saved a lot since we do not have to use two separate
parts. The fuel cost is also lower”
