The CROSS series B directional control valves provide good metering characteristics and long dependable service life. Optimum versatility is provided due to the many standard and optional features. Balanced spools are select-fit for minimum leakage and load holding checks prevent load drop when shifting. Parallel flow path permits spools to be operated independently or simultaneously.

SPOOL ACTION OPTIONS FOR ‘BA’
4 - POSITION FLOAT
KIT NO. 1V1600(SPOOL NOT INCLUDED)
This feature provides four handle positions,
of which three are standard double-acting with spring centring to neutral. The fourth position has a
detent to hold in ‘float’ position allowing the cylinder or motor to travel back and forth at will. When the spool is in this ‘float’ position, both cylinder ports and pump ports are open to tank.

DETENT WITH SPRING CENTRING
This feature allows spring centring to neutral with a detent for the ‘in’, ‘out’ position, or both the ‘in’ and ‘out’ positions. The one or two position detent with spring centring is desirable for the operation of hydraulic cylinders or motors. The one position detent provides a float position for a three-way spool in the ‘in’ or dump position. This detent feature is applicable where quick release and centring is needed or for good metering of flow before placing into detent.

SPOOL ACTION OPTIONS FOR ‘BA’
PRESSURE DETENT
KIT NO. 1V0642
BA Valves with three - position spools can be provided with this option on any or all spools. A pressure detent holds the spool in the ‘in’ position. ‘out’ position or both ‘in’ and ‘out’ positions. The detent is held until the cylinder or motor reaches a pre-set pressure, releasing the detent, allowing the spool to spring return to neutral. Field installation can be made only if valve already has this option.

CLOSED CENTRE OPTION - ASSEMBLY 1V0206
This option provides for a closed centre system by
plugging the open centre flow passage. If desired
at some future date, the valve may be converted to
open centre or power beyond operation. As shown
an additional outlet is provided to dump the oil from
the return passage only.
NOTE: 1R0035 No Relief Plug should be used with this option.

OPENCENTREPASSAGE
This component provides for conversion from
power beyond to closed centre usage to open
centre usage or vice versa. When ordering, the
conversion plug may be installed in lieu of the
power beyond or closed centre plugs. The optional
outlet necessitated by these options would remain
plumbed to tank. If at some future date the valve
needs to be converted to power beyond or closed
centre, it would only be necessary to remove the
conversion plug and install the desired option.

1V0208 - 3/4 NPTF1V0209 - SAE 101V0249 SAE 12
This option provides for proper hook-up of an additional valve down-stream from another valve. The power beyond sleeve prevents subjecting the exhaust or return passages and spool seals of the control valve to back pressure.
NOTE: Since the return passage is blocked from normal outlet, it is necessary to provide an additional outlet which is to be hooked up to tank or reservoir.
