MONOBLOCK TYPE
E0.02.0911.02.02 For more information: WWW.SALAMI.IT
GENERAL FEATURES
Among all hydraulic directional control valves used in the field of mobile equipment applications, the spool valve is
the most popular.
The monoblock valve type offers an excellent performance price ratio.
FEATURES
VDM6 directional control valve has the following:
cast-iron monoblock construction up to 6 spools
parallel circuit, load check valve protection on down-stream of the pressure "P" line
tandem circuit, only the first working section, l.c.v. protection + l.c.v. protection on down-stream of the "P" line
possibility of venting valve
possibility of power beyond
spool construction in steel, hardened and nichel-plated to obtain a higher surface hardness and a better corrosion
resistance
several types of spool: double, single acting, spool motor, float position etc.
minimum tolerance between the spools and the body to obtain a minimum internal leakage
interchangeabilty of all the spools
several spool control devices and spool positioning devices
VALVE AND DEVICE TYPES
In order to meet the most stringent demands and to offer a wider range of applications, the following types of valves
and devices are available:
Valves
direct main relief valve: controls the maximum pressure in the circuit when one or more spools are on end stroke
located on "A" port side, can be:
direct type version up to 375 bar - 5440 psi
electric venting valve is available as:
12 or 24 Vdc and normally open or normally closed versions
flow restrictor: directly fitted on the "A/B" ports orifice
hydraulic piloted load check valve on the "A/B" ports: built-in a manifold assembled on the top of the VDM6
Devices
handle controls
cross lever: allows to acting two spools with one manual joystick
cable remote control
control device for microswitches: for the operation with electric d.c. motor driven pumps at one or more rotation speeds
hydraulic kick-out: returns the spool automatically to the neutral position when the pre-set pressure of port "A" or "B" is exceeded
anti-tilt device: the spool returns automatically in neutral position when the pressure reaches a pre-set value to avoid cranes
from becoming unstable
pneumatic proportional control available also with float position
electropneumatic control
hydraulic proportional control available also with float position
direct electric on-off control with emergency manual device
electrohydraulic on-off and proportional control, available also for 1 working section monoblock
several spool positionings device to return the spool to neutral position or to lock the spool on working position
rotary control
