Robust 600 Series Switch and Test Valve

Engineered for heavy-duty industrial working conditions, this robust 600 Series switch and test valve is an integrated core hydraulic control component for polyurethane foaming systems. It integrates pipeline pressure detection, material circuit switching and equipment commissioning functions in one solid unit, widely adopted in PU production lines for thermal insulation panels, automotive foam accessories and composite building materials. Upgraded structurally to overcome traditional valve defects such as poor durability and cumbersome debugging, it delivers outstanding rigidity and impact resistance for frequent working condition switching and long-term non-stop operation. As the core control unit, the 600 Series Test & Switching Valve is fully compatible with complete PU Foaming Hydraulic Components and various linear mixing head hydraulic modules. It stably conveys low and high-viscosity polyols and isocyanates, fitting both intermittent and continuous foaming equipment of all…
