1: What is a safety valve?
A: A safety valve is a pressure relief device that automatically opens at a preset pressure to protect equipment from overpressure. Safety valves are designed for compressible media like steam, air, and gas. They open rapidly (pop action) and are governed by ASME Section VIII or Section I codes.
2. What is the difference between a safety valve and a relief valve?
A: Safety valves are for compressible fluids (steam, air, gas) and open with a quick pop action. Relief valves are for incompressible fluids (water, oil) and open proportionally. Safety relief valves can handle both.
3. What does set pressure mean?
A: Set pressure is the inlet pressure at which a safety valve begins to open under service conditions. It is the pressure at which the valve "pops" to relieve excess pressure, and is typically stamped on the valve nameplate.
4. How do I select the right safety valve for my application?
A: Selecting the right safety valve requires knowing your system's MAWP, required relieving capacity, media type (steam, air, liquid), temperature, and inlet/outlet connection sizes.
5. What materials are available?
A: Common body materials include bronze (steam/air up to 400°F), carbon steel (higher pressures/temperatures), and stainless steel (corrosive media).
6.Can I use a safety valve for liquid service?
A:Standard safety valves are for compressible media only. For liquid service, you need a relief valve or safety relief valve specifically rated for liquid.
