  • Piping System Layout and Plumbing Accessories

    6.1.7 Stop Check Valve . As we have seen so far, most valves are classified as either stop valves or check valves; however, some valves function either as a stop valve or as a check valve, depending upon the position of the valve stem. These valves are known as STOPCHECK VALVES. The cross section of two stop-check valves is shown in Figure 5-29.

    The valve opens to allow flow and closes to stop flow. They are also known as on/off service or block valves. These valves are often used with a manual hand wheel, but can be automated with an actuator. Start/stop valves are used when flow needs to be diverted or for mixing applications when exact measurements are not required.

  • How valves work | Types of valves - Explain that Stuff

    For example, if you have a steam engine powered by a water boiler in which steam is building up, but the pressure suddenly gets too high, you need a valve to blow open, let the steam escape, and release the pressure safely before the entire boiler explodes catastrophically. Valves that work in this way are called safety valves. They're designed
