The safety valve (overflow valve) in the rotary motor is installed at the top of the rotary motor, limiting the pressure in the rotary circuit to a set safe pressure range, reducing the impact during the start or stop of the rotary motor. The safety valve is a two-stage design, when the safety valve opens, it does not produce excessive pressure, therefore, when the rotary motor stops moving, there is little vibration load generated. Specifications: Customizable based on actual conditions.
