What device governs the hydraulic hose under pressure?

The pressure relief valve is designed to govern the hydraulic hose under pressure by controlling the maximum pressure in the hydraulic system. Its primary function is to prevent the pressure from exceeding a predetermined level, which protects the hydraulic components and the hoses from potential damage due to overpressure. When the system pressure reaches this threshold, the pressure relief valve opens to allow fluid to escape, thus relieving pressure and ensuring the system operates safely within designed limits.

This capability of the pressure relief valve is crucial in hydraulic systems, as excessive pressure can lead to hose ruptures, leaking fluids, or catastrophic failures in the machinery. Therefore, having a properly functioning pressure relief valve is essential for the safe operation of any equipment relying on hydraulic technology.
