Pressure relief valves are an essential safety component in systems subject to very high pressures. In high-pressure applications, it is crucial that the pressure level is maintained within defined limits to protect both equipment and personnel. HYDMOS Industriteknik offers pressure relief valves from Haskel and Butech, designed to operate stably and predictably in demanding high-pressure environments.
By integrating the correct pressure relief valve into the system, a controlled safety function is created that activates when the pressure exceeds a pre-set level. This reduces the risk of component failure, leakage, and unplanned downtime.
Managing pressure variations
A pressure relief valve is designed to open when the system pressure reaches a defined limit. Once the pressure exceeds this level, the valve discharges the medium in a controlled manner until the pressure returns to a safe operating range. The valve then closes again.
In high-pressure systems, this function is critical because pressure fluctuations can occur rapidly—for instance, during pump start-up, the closure of flow paths, or temperature changes. A correctly sized pressure relief valve ensures that these variations do not lead to overloading of pipes, fittings, or other valves within the system.
The valves are constructed with seals and materials adapted for high pressures and repetitive actuation. This makes them suitable for industrial environments where operational reliability and reproducible function are requirements.
Protection against unwanted spikes
Pressure relief valves are used in systems where:
In applications such as pressure test systems and gas booster applications, the pressure relief valve acts as a final safety barrier. It complements other valve types such as needle valves, ball valves, and check valves by activating when the pressure level exceeds the permissible limit.
It is important to distinguish between regulating valves and pressure relief valves. The latter is not intended for continuous pressure regulation, but rather to protect the system against unwanted spikes.
Part of the whole
In a well-designed high-pressure system, the pressure relief valve forms part of an overarching safety strategy. Placement, set pressure, and compatibility with other components must be considered as early as the design phase.
The valve should be sized based on:
Proper integration minimizes the risk of damage to pumps, fittings, and instrumentation. In turn, this contributes to a longer lifespan for the entire system and reduced maintenance costs.
