Pressure Relief Valve Learn about Safety Valve and
Safety valves. A safety valve is a rapid opening or pop up action pressure relief valve actuated by inlet static pressure. Safety valves are used primarily with compressible gasses. Particularly for steam and air services. Safety valves are classified according to the lift of disk and bore of the valve.

Engineering Essentials: Pressure Control Valves
They often are used as safety valves to prevent damage to components from high surge pressures, or to relieve pressure caused by thermal expansion in locked cylinders. The differential between cracking and full open pressure on spring loaded poppet relief valves is high. For this reason they are not recommended for precise pressure control
Liquid Safety Relief Valve
Safety relief valves should not be discharged prior to installation. Do not install safety relief valves prior to pressure testing a system. If safety relief valves have been installed prior to a system pressure test, remove them. In the event there is a discharge prior or during installation the valve will need to be replaced or recertified.
Check Valve an overview ScienceDirect Topics
Check valves differ significantly from gate and globe valves. Check valves are designed to prevent backflow. Backflow simply means the flow that has reversed itself within a pipe and begins to flow backward. There are many designs of check valves, but the two most common types are the swing check and the lift check. Check valves do not use handwheels to control the flow of a commodity
Control Valves and their Principles of Operation Piping
Control valves automatically regulate pressure and/or flow rate, and are available for any pressure. If different plant systems operate up to, and at pressure/temperature combinations that require Class 300 valves, sometimes (where the design permits), all control valves chosen will be Class 300 for interchange ability.

Valve Aerodynamic Noise Reduction Strategies Valin
There are two strategies for reducing control valve noise: 1. Source control, that is doing something to the valve to make it less noisy, and 2. Path control, that is doing something to prevent the noise from reaching the people who would be bothered by it. There are two methods that are employed for source control of aerodynamic noise, pressure drop staging and flow division.
