SV98-T39 Valve

SV98-T39 Valve symbol


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.

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.

• 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.

Operating Pressure: 45 bar (650 psi) at Ports 2 and 3; 3.4 bar (50 psi) at Port 1
Proof Pressure: 55 bar (800 psi) at Port 1; 172 bar (2500 psi) at Ports 2 and 3
Burst Pressure: 110 bar (650 psi) at Port 1; 345 bar (5000 psi) at Ports 2 and 3
