LF08‑01L Threaded Cartridge Valve with Handwheel
Product Overview
LF08‑01L is a 08‑size manually adjustable threaded cartridge throttle valve fitted with knurled adjustment handwheel for hydraulic system. It fits standard T4‑1 cartridge cavity inside manifold block. The handwheel structure allows convenient on‑site manual flow adjustment without extra tools. This cartridge valve controls oil‑circuit flow rate, so as to regulate actuator moving speed. Widely used for hydraulic power units, small lifting machinery, agricultural equipment and fixture hydraulic manifold blocks.
Main Technical Parameters

Working Principle
1. Rotate the knurled handwheel clockwise or counter‑clockwise to change the opening size of the internal throttling orifice.
2. By adjusting orifice opening, it restricts the passing‑through oil flow volume, thereby controlling the moving speed of hydraulic cylinder or hydraulic motor.
3. Keep stable flow‑limiting performance under continuous working condition, realize stepless speed regulation for hydraulic执行元件.
Core Advantages
1. Industry‑universal T4‑1 08‑size cartridge cavity, compatible with most standard manifold blocks, no re‑machining required.
2. Equipped with knurled handwheel, flow adjustment can be completed on‑site without spanner or screwdriver, convenient for commissioning.
3. Stepless flow adjustment, smooth speed control response.
4. Compact screw‑in cartridge construction, reduce external pipe connections, lower leakage risk.
5. Hardened internal components, long service life for mobile and industrial hydraulic system.
Application Scope
Hydraulic power packs, small lifting platforms, agricultural machinery, fixture hydraulic circuits, hydraulic equipment requiring manual on‑site flow & speed regulation.
