Accessory model: Y-1512-B
Safety protection function: When the system is working normally, the valve is closed. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure), the overflow is opened and overload protection is performed to prevent the system pressure from increasing (usually the set pressure of the relief valve is 10% to 20% higher than the maximum working pressure of the system) ).
