TECHNICAL FEATURESS

SERIES 1, CAVITY: T-10A2STAGE, SOLENOIDOPERATED

ADJUSTABLE RELIEF VALVE

TECHNICAL FEATURES

Solenoid-operated, 2-stage, adjustable balanced piston

relief cartridges are pressure regulating valves. Energizing

the solenoid activates or deactivates the relief function.

Four versions are available.

RVCM-LJ*

Function: The RVCM is normally in relief mode. The

pressure setting is adjustable (5). When the solenoid is

energized, the tube (4) moves and blocks the connection

between main chamber (3) and pilot stage (6). Without

pilot ow, the main chamber is closed. The valve blocks

the ow path from port 1 to port 2 like a spool-type

directional valve.

RVCK-LJ*

Function: The RVCK is normally vented. The pressure drop

from port 1 (supply, pump) to port 2 (tank) is typically

100 psi (see performance curves). When the solenoid

is energized, the tube (4) moves and blocks the direct

connection between main chamber (3) and tank (port 2).

Pilot ow can no longer ow to tank directly. The valve is

in relief mode. The pressure setting is adjustable (5).

RVCL-LJ*

Function: The RVCL is normally in relief mode. The

pressure setting is adjustable (5). When the solenoid is

energized, the tube moves and opens a direct connection

between main chamber (3) and tank (port 2). The valve is

now vented. Pressure drop from port 1 (supply, pump) to

port 2 (tank) is typically 100 psi (see performance curves).

RVCN-LJ*

Function: The RVCN is normally blocked. De-energized,

the valve blocks the ow path from port 1 to port 2 like

a spool-type directional valve. When the solenoid is

energized, the tube (4) moves and allows ow through

the main chamber (3) to the pilot stage (6). The valve is in

relief mode. The pressure setting is adjustable (5).

SYSTEM

FLeX Series

APPLICATIONS

PUMP START-UP CIRCUIT

The normally open ventable relief RVCK is the ideal valve to use

in a system when starting up a prime mover connected to a large

pump with load. Unloading the pump is good practice and will be

less stressful on the system. Since these valves can be switched at

pressure, once the prime mover is up to full speed, the relief valve

can be energized to build up system pressure. The pressure is user

adjustable up to 5000 psi.

RVCK-LJ*

PUMP START-UP FOR ON/OFF FAN DRIVE CONTROL

The ventable relief RVCL is normally in relief mode. It is another option

for pump start-up. Unlike the normally open RVCK, the RVCL is in relief

mode when de-energized for more energy savings during normal

system operation.

Because the RVCL is in relief mode when de-energized, it is only

necessary to power the solenoid when the valve needs to unload

during prime mover start up.

This makes the valve an obvious choice for a simple hydraulic on-o

fan drive circuit as shown here and is a better choice when safety

requires system pressure in the event of electric power loss.

RVCL-LJ*

CONVEYOR BELT MOTOR CONTROL

The blockable relief RVCM is normally in relief mode. When energized

the valve blocks ow like a spool type 2-position, 2-way valve. The

valve is ideal for circuits that require two pressure setting.

In the example of a conveyor belt, the high inertia load requires a high

pressure to accelerate from stop. When the conveyor is in motion and

motor speed is constant, a lower relief setting maintains motion at a

lower pressure.

Compared to a circuit with two relief valves and one solenoid-

operated directional valve, the blockable RVCM eliminates the need

for the directional valve, creating a much simpler two-valve solution

instead of three.

FLeX Series

APPLICATIONS

BI-DIRECTIONAL PUMP PRESSURE DIFFERENTIAL LIMIT

The blockable relief RVCM is normally in relief mode. The valve

can be used to limit the pressure dierential across the motor.

The relief valve setting then allows the motor to accelerate with a

limited torque using the controlled pressure, smoothing out the

load movement.

In a rectier circuit, the RVCM limits the torque of the motor in

both directions.

RVCM-LJ*

ADJUSTABLE COMPRESSION FOR MATERIAL COMPACTORS

& BAILING PRESSES

The RVCN is normally blocked and, when energized, turns into an

adjustable relief valve.

The valve can be used as a pilot-operated 2-position, 2-way valve

with high capacity. When energized, the relief function of the

valve can be used to avoid decompression shock. In a continuous

regeneration circuit, the valve can unload the rod end side of the

cylinder. Preloading the cylinder avoids the decompression shock.

And because the valve is adjustable, it can be adjusted to control the

amount of compression in the compactor or press when the cylinder

goes from regen to normal mode.
