Description
Product Description
The ASHUN SRV Series Solenoid Controlled Relief Valves serve as intelligent pressure management centers for hydraulic circuits. By perfectly integrating a solenoid directional valve with a pilot-operated relief valve, these products allow system pressure to be electrically unloaded when actuators are idle, significantly reducing pump energy consumption and hydraulic fluid heat generation. This no-load startup and standby mechanism establishes a robust and automated pressure defense, making them ideal choices for energy-efficient industrial power units and large-scale presses.
Product Features
- No-Load Startup Protection: Utilize electrical signals for unloading to significantly reduce motor and pump starting stress.
- Thermal Effect Suppression: Route high-pressure fluid directly to the tank during standby to effectively prevent circuit overheating.
- Composite Control Module: Perfectly integrate directional control and relief mechanisms into a single unit to maximize spatial efficiency.
- Strict Pressure Maintenance: Precision adjustment shafts provide stable settings to reliably meet the locking demands of advanced machinery.
