DESCRIPTION
An adjustable bypass-type cartridge valve designed to regulate priority
flow while bypassing excess flow regardless of load pressure.
OPERATION
The DFRA-100-3 maintains a constant flow within specified accuracies
from ¿ to ¬ regardless of downstream load pressure at ¬ or bypass leg
¡. When flow produces a minimum predetermined pressure differential
across the compensator spool control orifice, the spool shifts against the
spring force to throttle the flow and maintain the priority flow setting. The
cartridge’s flow may be adjusted -40% of maximum setting. Reverse flow
is not regulated.
FEATURES and BENEFITS
• Pressure-compensated.
• Quiet response.
• Bypass port ¡ may be fully pressurized.
• Hidden adjustment (tamper resistant) option.
• Aluminum knob and disc nut option.
• Adjustment may be locked in place.
• Industry common cavity.
• Compact size.
