XO-Z0216 Pilot-Operated Unloading Relief Valve | Automatic Unloading for Energy Savings
A pilot-operated unloading relief valve is a smart pressure control solution that combines traditional relief functionality with automatic unloading. When system pressure reaches the preset value, the valve opens and stays fully open, diverting pump flow directly to tank. This allows the pump to run at near-zero pressure — cutting energy use, reducing heat, and extending pump life.
Features
⚡ Maximize Energy Efficiency: Pump unloads to near-zero pressure — slashes power consumption and reduces system heat
🔄 Automatic On-Demand Cycling: Stays open after triggering, closes only when pressure drops to reset value — perfect for intermittent duty
🎯 Consistent Reset Pressure: Fixed low reset value (e.g., 45 psi) regardless of main pressure setting — ensures reliable reseating every cycle
📈 High-Flow Capacity: Pilot-operated design handles high flow rates up to 400 L/min
🛡️ Built for Tough Cycles: Hardened components withstand frequent pressure cycling in demanding applications
