Operation
The valve is designed to keep constant ow in C (3) and concurrently
discharge exceeding ow in R (2) for other applications. Best performance
of the valve is assured when the ow in E (1) is at least 10% bigger than
in C (3).
Pressure variations in C (3) and R (2) do not alter the constant ow in C
(3).
Make sure that a pressure relief valve is always used between the pump
and the valve.

Operation
The valve is designed to provide ow adjustment in C and concurrently
discharge exceeding ow in R for other applications. A pressure relief
valve provides control of the working pressure in C, while the solenoid
allows for checked ow cut-off in C and retrieving in R. Best performan-
ce of the valve is assured when the ow in E is at least 10% bigger than
in C and a minimum pressure of 7-10 bar (100-145 psi) is available in C
or R. Pressure variations in C do not alter the checked ow. Working
pressure in R can not exceed the rating value of the pressure relief valve
in C, or else the whole E ow would end into R. When cutting-off in C, a
crossing load loss of 7 bar (100 psi) and a constant few liters drain occur
in D due to the working pressure in R. Make sure that a pressure relief
valve is always used between the pump and the valve. The steel body
version is recommended for use to control hydraulic hammers.

The valve is designed to provide ow adjustment in C and concurrently

allows for checked ow cut-off in C and retrieving in R. Best performan-

pressure in R exceeding the rating value of the pressure relief valve in
C, is admissible. Cut-off in C is accompanied by a crossing load loss of
2 bar (30 psi), a constant very low drain in D and complete retrieving
of all drains in C. Make sure that a pressure relief valve is always used
between the pump and the valve.
