General valve description

The CV550 is a stackable parallel circuit valve available from 1-10 section per valve unit and can be configured for both fixed and variable pumps. It is designed to handle an input flow of up to 90 l/min [24 USgpm] and a working pressure of up to 350 bar [5000 psi]

The CV550 has a modular design with a range of different inlet-, section- and outlet modules which allows for a high level of customization of the valve unit. The compact size and the possibility for a large number of integrated features makes it ideal for a wide range of applications such as; truck mounted cranes, excavators, drilling rigs, tipper trucks etc.

The CV550 is manufactured using the highest quality alloy cast iron which in combination with NIMCO’s advanced machining and control methods assures the precise accuracy of every component. Each valve is tested and the results documented prior to despatch.

Minimized spool leakageHard chromium plated spools, low friction and a specially developed honing method gives absolute minimum spool leakage of the valve.

Excellent load controlCV550 can be fitted with the standard load control spools or with specially designed spools for specific flows, each of which is designed to provide optimum control characteristics within its flow range. On request, special spools can be designed for special functions.

Full utilisation of the spool strokeThe optimized metering grooves integrated in each spool and the precise machining of every component allows the entire stroke of the spool to be used. This allows full control of the load whether the operator is using very little or full flow capacity. In addition the movement of any spool in any direction will give the same speed of machine function, enhancing security and reliability.

Multifunctional controlSeveral spools can be operated at the same time even with very large differences in load pressures, due to the utilisation of the differential pressure built up inside the valve during operation.

Uniform and low lever forcesBy combining the unique design features of the valve body and the spools, an excellent balance of the dynamic forces is achieved throughout the entire pressure and flow range. This keeps spring forces at a minimum and makes the valve very easy to operate by hand lever as well as any of NIMCO’s remote controls.

Wide range of accessoriesThe CV 550 offers a wide range of possibilities by using existing and future accessory valves. Also a wide range of spool and remote controls such as single or joystick wire controls, pneumatic and hydraulic proportional or on/off controls are available.

IM1, 2 & 3 - Mid Inlet Modules

MODULE DESCRIPTIONThe CV550 can be equipped with a range of different mid inlet modules to feed the valve with more than one pump. There are three different modules for different circuit options. All mid inlet modules have the same width as a standard section, which means that the same tierods can be used to assemble the valve.

IM1 – Parallel CircuitMid inlet section designed so that the pump inlets are parallel connected. Can be equipped with a relief valve to handle the flow from the second pump. The Relief valve should be set at the same pressure as the relief valve in the side inlet module.

IM2 – Dual CircuitMid inlet section which is designed so that it divides the valve into separate circuits with a common tank return. This inlet can be equipped with a relief valve for the second pump. This means that the circuits can operate with different flows and system pressures.

IM3 – Tandem CircuitMid inlet section which is designed so that there is a tandem coupling between the two circuits. The first part of the valve is supplied only by the first pump. The second part (after the IM3) is supplied by both pumps

Standard Spools

All of NIMCO’s spools are designed for specific flow rates in order to achieve optimal load control characteristics and to fully utilise the entire stroke of the spool. By optimizing the balance between spools and valve housing, spring forces are minimized and exact manoeuvring is achieved. Besides the standard spools listed there are also special spools available. For further information concerning these types please contact your NIMCO representative.
