Flow Control <strong>Valves</strong><br />
SDR10A-01<br />
Needle, Free Reverse Flow<br />
Up to 42 gpm (160 l/min) • 5000 psi (350 bar)<br />
Hydraulic Symbol<br />
Description<br />
A screw-in cartridge, adjustable variable orifice, hydraulic flow restrictor valve<br />
with free reverse flow check, non-pressure compensated.<br />
2 1<br />
Operation<br />
The SDR10A-01 controls flow from port 2 to port 1 from fully open to leaktight<br />
shut-off by turning the adjustment feature clock-wise. Flow is non-pressure<br />
compensated. The flow from port 1 to port 2 is free.<br />
Features<br />
• All external surfaces zinc-plated<br />
• Adjustment needle cannot be backed out of the valve<br />
• Desired setting may be locked down<br />
• Complete shut-off<br />
• Hardened parts to ensure minimal wear and extend service life<br />
• Aluminum knob option for ease of adjustment<br />
• Industry common cavity<br />
