As our name suggests, we at Dalton Hydraulics specialize in providing hydraulic components of all kinds. If you use hydraulic equipment in your operation, then you can turn to us whenever you need replacement parts or new systems. In this article, we will focus on hydraulic pressure relief valves, explaining what they are and what purpose they serve in hydraulic mechanisms.
- What is a hydraulic pressure relief valve? – All hydraulic systems rely on pressurized fluid to power their mechanisms. The movement of the hydraulic fluid is used to make other parts of the machines move, delivering force in various ways at the end point. A hydraulic pressure relief valve is a component of a hydraulic mechanism whose purpose is to prevent excess pressure from building up, as too much pressure could damage the mechanism or cause it to malfunction.
- What is the purpose of a hydraulic pressure relief valve? – As we alluded to above, the purpose of a hydraulic pressure relief valve is to give excess pressure a way to escape. This acts as a safety measure which keeps the mechanism working properly, preventing it from malfunctioning.
- How does a hydraulic pressure relief valve work? – A hydraulic pressure relief valve consists of an oil inlet with a valve poppet connected to a spring, which in turn is encased in a valve housing that is connected to an oil outlet. When enough pressure builds up in the hydraulic fluid system to compress the spring, the valve opens, allowing excess fluid to exit the system and thus releasing excess pressure.
