The rated relief pressure of the valve is generally set at a specific value, such as [X] MPa (megapascals). This value is determined based on the maximum allowable pressure of the rotary hydraulic system and the design requirements of the rotary motor and associated components. It serves as the critical point at which the valve starts to operate to protect the system.
(Pressure Adjustment Range)
The rotary relief valve typically provides a certain range for pressure adjustment to adapt to different operating scenarios and requirements. The adjustment range might be from [minimum adjustable pressure] MPa to [maximum adjustable pressure] MPa. This allows for fine - tuning the relief pressure according to the specific needs of the excavator's rotary operations, such as different rotational speeds or load conditions.
(Pressure Overshoot)
In case of a rapid pressure increase, the valve is designed to limit the pressure overshoot to a maximum of [Y] MPa above the set relief pressure. This characteristic helps to prevent sudden and excessive pressure spikes from harming the hydraulic components, ensuring a more controlled and stable pressure - relief process.
