301.07.0066 Pressure Limiting Valve - CASE DAF IVECO

The pressure regulation of heavy commercial vehicle pneumatic systems requires absolute precision and reliability. This high-strength component is designed to manage pressure fluctuations effectively within the brake system. With its specialized internal construction, it ensures stable performance under demanding operational conditions.

301.07.0066 is the OE equivalent of the WABCO 475 010 302 0 pressure limiting valve used in DAF, IVECO, SCANIA, and VOLVO heavy commercial vehicles. This part is engineered to meet the stringent requirements of major manufacturers including CASE (3404140R91, 4304140R91), LIEBHERR (5029651, 5029663, 5029667, 5029678, 5029834, 502983408, 502983977, 5029993), and MERCEDES BENZ (001 429 90 44). It also provides compatibility for specialized applications involving MAN (81.52101-6058, 81.52161-6054) and RENAULT TRUCKS (5000438152, 5000442713, 5000607007).

Workshop technicians should note the specific technical configuration: both ports utilize M22x1,5 threading to ensure a secure and leak-free assembly. The device operates with an inlet pressure of 7,5 BAR and maintains a precise adjustment range between 1,2 and 6,2 BAR to achieve the target outlet pressure of 5,3 BAR. Proper installation and regular maintenance of the pneumatic lines are essential to maintain optimal system functionality.

Regular inspections of the pressure regulation components can prevent unexpected downtime in fleet operations. This part serves as a critical element in ensuring the safety and efficiency of the braking system in heavy-duty trucks and construction machinery.
