SV98-T40 Valve

SV98-T40 Valve symbol


An economical drop-in-style, flange-mounted, direct-acting, balanced spool,
two-position, four-way, directional control valve. It can be specified for use in
specialized low-pressure pilot systems or power shift transmission control or
as a displacement control valve for turbocharger applications. The coil is an
integral part of the valve and is not serviceable.

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.

• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• 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.
