ZX70 Main Control Relief Valve

The ZX70 Main Control Relief Valve is a core pressure regulation component for small construction machinery and precision industrial hydraulic systems. Tailored for lightweight heavy-duty conditions, frequent start-stop and precision pressure stabilization scenarios, it is widely applied in small-scale engineering hydraulic equipment, precision PU foaming production lines and automated hydraulic units. It undertakes core functions of main pressure locking, instantaneous overpressure relief and pipeline pressure balance, effectively eliminating common defects such as unstable pressure holding, delayed relief and low micro-adjustment accuracy to ensure stable hydraulic system operation. Fully compatible with complete PU Foaming Hydraulic Components, it seamlessly matches hydraulic modules of precision foaming equipment and adapts to low and high-viscosity PU material delivery for intermittent and continuous production. Cooperating with the Hydraulic Safety Valve, it forms a comprehensiv…
