Frequently Asked Questions(FAQ) about Duplex Stainless Steel Direct Acting Pressure Relief Valve

Q1: Why is Duplex Stainless Steel an ideal material for pressure relief valves?

Duplex stainless steel combines high strength with excellent corrosion resistance, particularly against seawater and chloride-induced stress cracking. This makes it highly suitable for demanding environments, such as desalination plants, offshore platforms, and marine pipelines. Compared to conventional stainless steels, duplex stainless steel offers an extended service life and reduces maintenance requirements.

Q2: What is the difference between a pressure relief valve and a safety valve?

Although both valves are designed to protect systems from overpressure, their applications differ. A pressure relief valve (PRV) is typically used in liquid systems and gradually releases excess pressure to maintain safe operating conditions. In contrast, a safety valve is designed for gases or steam and opens fully and immediately when the set pressure is exceeded, ensuring rapid pressure discharge.
