Sandsun VA08 is a standard hydraulic overload protector series (Standard type), using compressed air for control, optimally designed for press machines with a capacity of under 200 tons. This is an indispensable device to ensure operational safety and extend the lifespan of the press system.
Sandsun VA08 - Reliable protection for presses < 200 tons.
The system operates based on the principle of monitoring hydraulic pressure in the slide cylinder. Upon detecting an overload, the valve immediately releases pressure within 3/1000 seconds, while simultaneously emitting an emergency stop signal. Subsequently, the integrated air pump automatically recharges to normal working pressure.
✨Key Features of the VA08 Series
1. Instant Response
Pressure release time is only 0.003 seconds, completely eliminating excess stamping force as soon as an incident occurs.
2. Automatic Pressure Regulation
The internal pressure control valve automatically adjusts to compensate for pressure increases due to rising oil temperature during operation.
3. Rapid Recovery
Uses compressed air to automatically refill oil, helping the press machine quickly return to a ready-to-work state.
