Directional control valves with up to 6 individual applications per assembly by Brand Hydraulics

Brand Hydraulics introduces direct acting solenoid operated stackable directional control valve

The Brand, Series 21 Direct Acting Solenoid Operated Stackable Directional Control Valves are assembled on demand on customer’s requirements for up to six individual applications per assembly.

When assembled in their normal manner the Series 21 spool sections are in parallel. When the spools are in the neutral position flow passes by each spool and then onto the tank (outlet) port. If two or more spools are shifted simultaneously their work ports are in parallel. The oil flow will take the path of least resistance allowing lighter loads to move first.

OUTLETS – are available end ported (1) which is not convertible to top or side porting. The other optional outlets are top (2) and side (3) ported, these two options are field convertible to all three ports. Options (2) and (3) are machined for power beyond and closed center cartridge. Specify (W) to receive the outlet assembled with power beyond cartridge. Specify (C) to receive the outlet assembled with closed center cartridge.

WORK SECTIONS:
Note: Series 21 work sections can be combined with series 20 work sections on the same stack. (See series
20 literature for ordering information)

SPOOL TYPE – Open center four-way (O4) connects ports A and B to tank in neutral. Tandem center four-way (T4) blocks port A and B in neutral. Tandem center three-way (T3) powers a cylinder in one direction. Please note that closed center four-way operation can be obtained by using a tandem center fourway spool and a closed center plug in the assembly’s outlet section.

ACTUATORS – Option (E) specifies electric control only. Option (L) specifies electric control with manual lever override for use when power is unavailable. Please note the lever does not shift when valve’s spool is shifted electrically. Option (M) specifies electric control and push pin style manual override. This option also allows the customer to shift the spool when power is unavailable.

VOLTAGE – Option (A) is 12 volt DC with DIN 43650 connector.
