The most commonly used pressure rating is the PN25. But the valves can be made up of different material types based on the applications pressure and temperature requirements with corrosion resistance demands. The operating temperature varies from -20 degrees to 198 degrees Celsius for the general purpose Screw-Down Stop Check Valve where higher and lower temperatures are possible with higher alloy material made valves. The size of the valve can also range based on the application requirements with the JIS F7471 Screw Down Non-Return Valve pressures ranging from 150lb to 2500lb and a range of pressure numbers up to PN160.
