A pressure release valve is an instrument used for limiting the amount of pressure in a machine so that it does not build up and cause safety hazards. This can be used both for liquids such as water and for various gases. They are perhaps most commonly used in residential water heaters, to prevent liquid from building up and causing issues down the line. For both residential and commercial needs, they are an extremely vital tool for workplace or domestic safety, as their primary purpose is to ensure the safety of otherwise dangerous machines and instruments. A pressure reducing valve is an essential tool for many projects and finding pressure relief valve suppliers who can help you find the right option is critical. At Teltherm Instruments, we do just this and supply a variety of gas and water pressure reducing valve options for your residential or commercial needs.

How Does a Pressure Reducing Valve Work and When Do I Need One?

You can utilise pressure relief valves in any number of circumstances, for both commercial and industrial machines applying hydraulics. Finding the right valve for you depends on how you’re going to use it, and where it will fit. For instance, there is a vast difference between high and “low rate” pressure scenarios, and different valves work in different situations. Fortunately, there is a range of pressure relief valves, in all shapes and sizes, available online.

A pressure-reducing valve is usually an open, 2-way valve that allows pressurised fluid to flow in and out until it reaches another chamber. The valve then regulates the flowing substances until the desired pressure is reached. This systems works the same for both gases and liquids and can be utilised on either. As such, it monitors and reduces pressure when necessary, and keeps liquid or gas pressures at safe, normal levels to ensure safety in the workplace or at home.

There are plenty of advantages to using a pressure reducing valve. For example, they operate in high temperatures and across different levels of pressure and are incredibly efficient. They are compatible with a wide range of chemicals and are made in standard piping dimensions, so you don’t have to worry if they will fit or work in your setting. They are also reasonably affordable and make for a convenient way to remain safe while working.
