Sectional Control Valve

TRS20 Series Flow‑Sharing Sectional Valve

Product Brief

TRS20 is a high‑flow LUDV flow‑sharing sectional valve with modular sandwich‑plate design. Max 10 working sections are available. It works well with both load‑sensing variable pumps and fixed‑displacement pumps. Multiple control modes including hydraulic pilot, manual, electro‑proportional and on‑off solenoid are supported. It features load‑holding and individual section priority adjustment, widely adopted on medium‑heavy construction machinery.

Key Features

1. Modular Sandwich‑plate Structure：Flexible section combination on demand, up to 10 working sections for different machine configurations.

2. LUDV Load‑independent Flow Sharing：Built‑in load pressure compensation. Flow distribution for multiple actuators is independent of load pressure, ensuring smooth simultaneous movements.

3. Multiple Control Options：Hydraulic pilot, manual, combined manual‑pilot control; Electro‑proportional / on‑off solenoid control (ATEX explosion‑proof versions optional).

4. Load‑holding Function：Integrated load‑holding check valves prevent cylinder drifting, improving safety for boom and lifting applications.

5. Adjustable Section Priority：Action priority can be set individually for each spool section to meet custom machine logic.

6. Multi‑stage Pressure Protection：Main LS relief valve limits system maximum pressure. Secondary relief valves on each section protect actuators from overload separately.

7. Low Pressure Drop & Energy‑saving：Optimized internal flow passages reduce pressure loss, lowering fuel consumption and improving overall efficiency.

8. Superior Handling Performance：Excellent inching capability, comfortable operation. High repeat accuracy with low hysteresis for stable proportional output.

9. Rugged for Harsh Conditions：Compatible with mineral hydraulic oil; Permitted contamination level NAS1638‑9; IP69K protection grade for outdoor site environment.
