Sandsun VA12 is a standard hydraulic overload protector series of the pneumatic type (Air Type), specifically designed to meet the protection requirements for press machines with capacities from 200 tons to 600 tons. With the ability to handle large oil flows, VA12 ensures rapid and reliable response even with large cylinder systems.
Sandsun VA12 with integrated oil tank.
The VA12 system comes integrated with necessary control units including a pneumatic regulator, solenoid valve, and pressure gauge, making installation and operation simpler. When an overload occurs, pressure is released almost instantaneously, protecting the press machine and die from costly damage.
✨Key Features of the VA12 Series
1. Large Flow Discharge
Designed for larger press machines, VA12 is capable of discharging oil at a flow rate of up to 39000 cm³/sec, ensuring instant pressure relief.
2. Integrated Control Unit
Comes with necessary pneumatic control components, simplifying the system and saving installation space.
3. Auto Recovery
The system automatically refills hydraulic pressure after discharge using compressed air, helping the machine quickly return to a ready state.
