Import Basic Electro Hydraulic Training System — Buy in wholesale FOB from Supplier in China

The Basic Electro Hydraulic Training System from Dolang Technology & Equipment Co., Ltd. is a modular bench unit designed for polytechnic and university-level instruction in combined electrical and hydraulic control. The system covers three principal domains: basic electric control (including AND/OR logic, relay self-locking, and proximity sensor applications), hydraulic control circuits (manual and solenoid valve reversing, locking, and unloading), and pressure/flow control circuits (single and two-stage pressure regulation, pressure reducing, sequence valve balance, and throttle-based speed control). The source description details 13 experiment categories, though buyers should request a formal experiment manual to confirm the exact circuit diagrams and component lists provided.

The hydraulic side of the system is built around industrial-standard components: manual shuttle valves, solenoid directional valves, pilot relief valves, sequence valves, throttle valves, and speed regulator valves. These are typical of ISO 4401 CETOP-pattern valves used in mobile and industrial hydraulics training. The electrical portion employs relays, proximity sensors, and pressure relays to demonstrate control logic integration. Standard training systems in this class operate with mineral oil hydraulic fluid at pressures up to 6.3 MPa (630 bar is atypical for training equipment; 6.3 MPa or 63 bar is more common, so confirm the actual working pressure rating with the supplier). The aluminium or steel manifold block construction is standard for educational hydraulic trainers to minimise leakage and simplify circuit reconfiguration.

Purchasers are typically technical colleges, university engineering departments, and industrial training centres that need to teach the intersection of electrical control and fluid power. The system supports experiments in meter-in, meter-out, and bypass这三大调速回路 (bypass throttle speed regulation), as well as parallel and series configurations of speed regulator valves. When sourcing, confirm whether the unit includes a dedicated hydraulic power pack with reservoir, pump, and motor, or whether that must be sourced separately. Also verify the maximum working pressure, reservoir capacity, and whether the system uses standard ISO 4401 porting to allow substitution of real industrial components for advanced student projects.

Dolang Technology & Equipment Co., Ltd. is headquartered at No. 18-2 Lashan Hi-Tech Industrial Park, Jinan, Shandong, 250022, China. The company holds a harbor trust tier. The response rate is recorded at 0.00 percent with zero average response hours, indicating no tracked messaging activity through the platform. Buyers should therefore establish direct contact via the Jinan address or an independent channel to discuss technical requirements and assess responsiveness before relying solely on platform messaging.

The listing presents a detailed experiment list for an electro-hydraulic training system, suggesting specialisation in industrial education equipment. No company history, factory scale, annual revenue, employee count, or client reference is provided in the source data. Shandong Province has a significant cluster of educational and industrial automation equipment manufacturers. Prospective buyers should request a company profile, ISO 9001 or equivalent quality system certification, and evidence of export experience, particularly for compliance with destination-country electrical and machinery safety regulations.
