What is the purpose of a pressure relief valve?

There are several industrial mechanisms where pressure plays an important role. To control the pressure in many of these mechanisms, a pressure relief valve produced by safety relief valve manufacturers is sought.

Pressure Safety Valve (PSV), Relief Valve and Pressure Relief Valve (PRV) are different names of a safety valve, a component used for controlling pressure. The PSV is used mainly in industries such as chemicals, petrochemicals, natural gas processing, etc.

Ensure safety with a pressure relief valve

The pressure relief valve is a safety valve that keeps the pressure within safety limits to prevent equipment failure, mishaps or other undesirable outcomes. Pressure relief valves are designed with controls to increase or decrease the level of pressure in a pressure vessel.

The safety relief valve ensures safer management of the environment if excess of pressure or overpressure situation occurs wherein the pressure increases beyond the Maximum Allowable Working Pressure (MAWP). The excess pressure generated is diverted into a safer outlet through an auxiliary route.

An automatic safety relief valve also functions effectively in the absence of a power by tracking the process fluid movement in the pipeline. For example, even during a power failure, the LPG passing through a LPG pipeline can be automatically shut off with the help of a functional safety relief valve if excess liquid flow is detected in the event of a leakage in the line.

For the safety valve to deliver optimum performance, it should be installed and maintained properly. Use of a pressure relief valve with an incorrect size can also lead to damage to life and property in the vicinity. Pressure relief valve manufacturershave to run a number of tests to design and build the valves with the right specification.

Finding the right pressure relief valves

Depending on the contents to be passed through the valve, the material of the valve can be decided. Materials such as Stainless Steel, Brass and Carbon are some of the material options. Although there are standard valve sizes available in the market, the valve can be custom-designed along with desired end connection types to get the right fit for the intended mechanism.

Pressure relief valve manufacturers usually have a team of engineering design experts who discuss the requirement with the client for customised valve designs. Depending on the application, a pop action safety valve or angle type discharge valve can be used. The pressure range can be customised as per the specifications of the pressurized area. High-quality pressure relief valves require low maintenance and therefore, lead to minimal costs.

For pipelines carrying LPG and other gases, safety risks are averted by using valves. Whether it is an industrial plant, a commercial space or a residential complex, reliable safety relief valve manufacturers are well-equipped with the necessary infrastructure and the teams to ensure minimum wastage of energy and maximum safety in handling of contents.

Certified valves are provided by expert manufacturers who study the requirements of the clients and offer a cost-effective solution with the necessary test certificates from industry-recognized certifying agencies. For reliable safety relief valves, get in touch with AEPL at www.aeplglobe.com.
