Four-Position Hydraulic Circuit Shut-Off Valve Anatomical Model

Product Overview:

This product is a dedicated anatomical teaching model of a four-position hydraulic shut-off valve (four-way four-position directional valve). Based on precise cross-sectional machining of a real valve assembly, it is specifically designed for integrated theory and practice teaching, practical training demonstrations, and skills assessments in automotive, construction machinery, and hydraulic transmission majors. Its core value lies in visualizing the complex internal structure, hydraulic circuit switching logic, and working principle of hydraulic valves, solving the teaching pain point of "not being able to see or understand" real valves, and helping students quickly master the structural understanding, principle comprehension, and fault analysis capabilities of four-position valves.

Features:
1. Uses a four-position hydraulic shut-off valve assembly (with complete accessories) for dissection, with all components present, comprehensively showcasing the internal and external structure of the assembly.

2. Through dissection and different colors painted on each section, the mechanical structure of the internal and external components and their assembly relationships are clearly displayed.

3. The equipment base frame (with anti-vibration pads) is made of 1.5mm cold-rolled steel sheet, stamped and coated. The anti-vibration pads are fixed to the base with M6*4 screws.
