LV -- GENERAL INFORMATION
The Brand, loader directional control valve is available in a two (LV22) spool configurations. The LV offers parallel, tandem center 4-way float, open center 4-way (motor spool), regen and tandem 3-way spools. The valve is also field convertible to closed center or power beyond with appropriate cartridge.
SPOOLS – Tandem center 4-way (T) powers a cylinder or a motor in both directions. Regen 4-way (R) acts just like a Tandem spool in the standard three position, but also has a fourth position that allows for rapid extension of a cylinder (available on first spool of LV22 only, use with FS spool action). Open center 4-way (O) connects all ports to tank when in neutral. Tandem center 3-way (T3) powers a cylinder in one direction.
SPOOL ACTION – Three position detent (D) holds the spool in neutral and both active positions. Friction detent (F1) applies friction to the spool so that the spool does not move when the handle is released, a detent groove clearly indicates neutral position. Spring center (S) returns the handle to neutral when the handle is released. Fourth position spring centering (FS) is similar to spring center except it has a fourth position that allows a cylinder to rapidly extend (with regen spool in first location only). Spring center detent (SD) springs back to neutral from one position and is mechanically detented in the other position. Fourth position float (K) is similar to spring center except it has a fourth position detent that makes all ports common to each other (with tandem center spool in last spool location only).
ACTUATORS – Standard joystick handle (A) is used to actuate two adjacent spools with one handle. Optional joystick handle (A1) is used to actuate two adjacent spools with one handle (See joystick diagram on page three). Enclosed lever handle (L) pressurizes the B port when the handle is pushed towards the valve body. No actuator (N) is used when it is necessary to connect the spool to an external actuator
OPTIONS – Power beyond (W) offers high pressure carryover for valves down stream. The LV series is also field convertible to power beyond with sleeve kit (LV2-W). Closed center (C) blocks the neutral flow path. The LV series is also field convertible to closed center with closed center kit (LV2-C). Adjustable relief (B) is available in pressure intervals of 100 psi (6.9 bar) (2000 psi standard relief setting and 600 to 3200 psi setting range).
