In critical supply pipelines with very sensitive old pipeline infrastructure, pressure reducing valves are often supplied on-line. This helps to ensure pipeline pressures operate at lower, safer working conditions. Pressure relief valves are often fitted immediately downstream of a pressure reducing valve; this relieves any excessive pressure in the event of PRV failure or a rapid decrease in supply downstream.

Our easy to install Floor Heating kits are fully controllable from our digital thermostat controllers, that cover areas up to 23m2, and are a great option if you are renovating a bathroom or a room which is going to be tiled or screeded.

A pressure relief valve is typically installed on a tee off a main supply pipeline. Pressure release valves are designed to open and discharge excessive pressure above the valve set point, either to atmosphere the pressure or pipe it away to a different location.

In any pressure reducing station, it’s critical to ensure that the downstream pressure is kept at a constant in all flow conditions, regardless of demand. Understanding the need for a...

In larger pipelines, there may be many components in a network that generate rapid reduction in flows. In turn, these rapid reductions in flow generate pressure spikes. Often, a pressure relief valve is installed close to the problematic components to relieve the excess pressure.

Often in a fixed-speed pump under low demand times, a pump can run back on its curve to a point that is underisable as the pressure rises. This creates the potential for the water to increase in temperature. In these instances, a circulating pressure relief valve is used to keep the pressure at a safe working level, and to protect the pump.

In this piece, you’ll learn why pressure relief valves are useful, find recommendations for a range of models depending on your application and objectives, and learn how to choose the...
