SV98-T39 Valve

SYMBOL:
SV98-T39 Valve symbol

 

DESCRIPTION
An economical drop-in-style, flange-mounted, direct-acting, balanced spool, two-position, three-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.

OPERATION
When de-energized, the SV98-T39 allows flow from 2 to 1, while blocking flow at 3. When energized, the cartridge’s spool shifts to open from 3 to 2, while blocking flow out 1. 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
• 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.
