The LDPR-10-21 is an L Series direct acting pressure reducing and relieving cartridge valve for a C10-3 cavity. Its setting adjusts from 400 to 2,100 psi. The valve is rated for 6 gpm and a 3,000 psi operating pressure, with an anodized aluminum alloy body rated for -30°F to +250°F.
The job of a reducing valve is to hold one branch of a circuit at a lower pressure than the rest. As pressure at the reduced port climbs toward the setting, the spool restricts flow from the inlet and holds the branch there, even when supply pressure is higher. The relieving function covers pressure that builds from the downstream side: above the setting, the valve opens the branch to tank and brings it back down.
In a direct acting design, the adjusting spring acts on the spool itself, with no separate pilot stage. The 400 to 2,100 psi range covers mid-pressure branches within the 3,000 psi rating.
The valve uses three ports: inlet, reduced pressure outlet and tank. No ported body is listed for this part number, so it fits a manifold or line body machined for the C10-3 cavity. Confirm your cavity, flow and setting range before ordering.
