600 Series Switch & Test Hydraulic Valve

The 600 Series Switch & Test Hydraulic Valve is an integrated core control valve for PU foaming hydraulic systems, combining pipeline pressure testing, material circuit switching and system commissioning in one compact unit. Professionally designed for continuous and intermittent precision PU foaming lines, it is widely used in insulation panels, automotive foam parts and composite profile production. It eliminates common drawbacks of traditional split structures such as complicated commissioning, frequent downtime and inaccurate pressure calibration, greatly improving system flexibility and production continuity. As the central control component, the 600 Series Test & Switching Valve is fully compatible with complete PU Foaming Hydraulic Components and matches all linear mixing head hydraulic modules. It adapts to low and high-viscosity polyol and isocyanate delivery, fitting both small and large-scale foaming equipment. Working in coordination with the Hydraulic Safety Valv…
