Features
TRP12 Series Load‑Sensing Sectional Valve
Product Brief
TRP12 is a LS load‑sensing sectional valve adopting modular sandwich‑plate construction, supporting up to 12 working sections. It is compatible with open‑center fixed‑displacement pump systems and closed‑center variable‑displacement pump systems. Multiple control modes are available: manual, hydraulic pilot, electro‑proportional, on‑off solenoid and ATEX explosion‑proof options. Equipped with multi‑level safety protection and high control accuracy, it is widely used for aerial work platforms, agricultural machinery, mining and other medium‑light mobile hydraulic machinery.
Modular sandwich‑plate design, 1‑12 sections configurable
Load‑sensing compensation, fits open‑center & closed‑center systems
Multiple control modes: manual, hydraulic pilot, electro‑proportional, ATEX optional
Multi‑stage safety protection with per‑section pressure limiting
Stable proportional output, high repeat accuracy & low hysteresis
IP69K protection, robust for harsh mobile‑machinery working conditions
