The LDPR-10-4 is an L Series direct acting pressure reducing and relieving cartridge valve for a C10-3 cavity. Its reduced pressure setting adjusts from 80 to 400 psi. It handles 6 gpm and carries a 3,000 psi operating pressure rating, with an anodized aluminum alloy body rated for -30°F to +250°F.
A pressure reducing valve holds a branch circuit at a lower pressure than the main system. As downstream pressure rises toward the setting, the spool moves to restrict inlet flow, so the branch stays at the set pressure even when supply pressure is higher. The relieving function covers the opposite case: if something pushes downstream pressure above the setting, the valve opens the branch to tank and brings it back down.
Direct acting means the adjusting spring works on the spool itself, with no separate pilot stage. That keeps the cartridge short and simple.
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. Pick the setting range that brackets the pressure your branch needs; this part number covers 80 to 400 psi.
