DESCRIPTION
An economical drop-in-style, direct-acting, balanced spool, 2-position, 4-way,
directional control valve. It is well suited for use in specialized low-pressure pilot
systems or power shift transmission control.
OPERATION
When de-energized, the SV98-T40 allows flow from 3 to 2 and from 4 to 1.
When energized, the cartridge’s spool shifts to allow flow from 2 to 1 and from 3 to 4.
Pressure at 1 (tank) should not exceed 3.4 bar (50 psi).
NOTE: The coil is an integral part of the valve and is not serviceable.
FEATURES
• Economical drop-in style.
• Integral waterproof coil standard; see page 3.400.1_pdf for a description
• of tests conducted to verify coil waterproofing.
• 12 VDC or 24 VDC coils.
• Several push-on termination options.
