Valve

Product advantages

• Pressure compensated
• For both fixed and variable pumps
• Post compensated
• If 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.

4
Product advantages

• Inlet variable pump with emergency stop function
• Shuts down the flow into the valve and drains
  the valve internally so that no pressure will be
  built up
• Inlet fixed pump with electric unloading
• Saves energy and avoids pressure to be built up
  in the valve

5
Product advantages

• Pressure limiter
• Sets the maximum pressure individually on each
  port
• - Port specific shock/anticavitation valve for
  each section module
• Port 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

6
Product advantages

• - Pressure limit for each section
• Limits the load pressure out on each section
• - External control of the port pressure
• The 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 limiter
• Sets the maximum flow for each section
• - Float Position option
• Decouples the hydraulics from he loader and the
  machine follows the profile of the ground

7
Product advantages

• High Pressure Carry Over
• Used 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 control
• Easy to convert from electronic to hydraulic
  control. All that needs to be done is to exchange
  the solenoid valve for an adaptor

Customer reference
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 competitors
products. We have saved a lot since we do not
have to use two separate parts. The fuel cost is
also lower -Neil Suitor, McCloskey
