    Watts was previously based in Lawrence, MA. [3] [4] Watts created a type of safety valve known as the temperature and pressure valve (T&P valve), which was used for safely venting hot-water supply tank systems, reducing the risk of explosion. [5] By the time of World War II, the U.S. Army required Watts T&P valves on all army hot-water supply ...

    The fill valve in a toilet water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank. In some valve designs, the pressure of the flow fluid itself or pressure difference of the flow fluid between the ports automatically controls flow through the valve.

  7. Globe valve - Wikipedia

    en.wikipedia.org/wiki/Globe_valve

    Globe valves with ports at such an angle are called angle globe valves. Globe valves are mainly used for corrosive or highly viscous fluids that solidify at room temperature. This is because straight valves are designed so that the outlet pipe is in line with the inlet pipe and the fluid has a good chance of staying there in the case of ...
