Sun Hydraulics RDFALWN Relief Valve
Sun Hydraulics RDFALWN Relief Valve
Product Description :
- It is a critical component in hydraulic systems designed to protect the system from overpressurization.The primary function of a relief valve is to limit the maximum pressure in a hydraulic system by diverting excess fluid when the pressure exceeds a predetermined level. This helps prevent damage to the system components due to excessive pressure.
- These valves used to protect hydraulic components from pressure transients.
- The seals on the adjust screw are exposed to system pressure which means this valve can only be adjusted when the pressure is removed. The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting.
