SV98-G38 Valve

SYMBOL:
SV98-G38 Valve symbol
DESCRIPTION
A direct-acting, spool-type, two-position, three-way, directional control valve. It is a drop-in,
flange-mounted, cartridge type valve for use with general purpose hydraulic fluids. The coil is
an integral part of the valve and is not serviceable.

OPERATION
When de-energized, the SV98-G38 allows flow from 1 to 3 while blocking flow at 2.
When energized, the spool shifts to open from 2 to 1, while blocking flow at 3.

FEATURES
• Bi-directional operation.
• Reduced leakage.
• Low pressure drop
• Economical drop-in style.
• Fast response.
• Corrosion-resistant plating.
• Inlet port screen option for additional resistance to contamination.
• Higher flow capacity at lower temperatures.
• Integral waterproof coil standard.
   See page 3.400.1 for a description of tests conducted to verify coil waterproofing.
• Coil voltage range from 10 to 28 VDC.
• Top-mounted coil with several push-on termination options.
• Round flange with optional mounting plates provides more options for orientation.
• Retrofit mounting options also available.
