The purpose of a plastic pressure relief valve is to protect equipment and systems from over-pressure or pressure surges. Plastic relief valves will open to release excess pressure and close once normal conditions are restored. It is important to remember that a plastic pressure reducing valve is a safety feature rather than a process valve and should be treated as such in order to ensure functionality.
Plastic relief valves are able to handle various types of media, including highly corrosive gas or liquids. Available in a range of plastic materials, including superFLO and uPVC, these highly robust valves will improve machinery service life and minimise downtime and maintenance costs. PVC pressure relief valves also have the ability to maintain back pressure in a closed-loop system, in order to make pumps run smoothly.
Durapipe are leading manufacturers of plastic pressure relief valves, developing a range of innovative plastic relief valves for effective machine functionality. Available in a range of sizes, from ½” up to 2” and 16mm up to 63mm, plastic pressure reducing valves are capable of relieving pressure between 0-10bar and allows back pressure between 0-3 bar.
