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 ...
In the case of the downstream check valve passing, the differential pressure relief valve prevents the possibility of the chamber pressure from exceeding the supply pressure. It is theoretically possible that, when both valves are faulty, backflow could occur, should the reverse flow rate exceed the capacity of the relief valve.
Each fixture usually has a characteristic means of connection. Normal plumbing practice is to install a valve on each water supply line before the fixture, and this is most commonly termed a stop or "service valve". The water supply to some fixtures is cold water only (such as water closets and urinals). Most fixtures also have a hot water supply.
The pressure-balanced shower valve compensates for changes in water pressure. It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure. As water pressure drops on one supply line, the valve reduces the pressure in the other supply line to match.
A separate actuator on the piping releases pressure in the line if it crosses a threshold. This releases the pressure on the back of the seal, causing the valve to open. The essential parts of a PORV are a pilot valve (or control pilot), a main valve , a pilot tube, the dome, a disc or piston, and a seat.
Leslie was purchased in 1989 by Watts Industries, Inc. of Andover, Massachusetts, which made water valves and was trying to increase its share of the valve industry. Leslie's 1988 sales were $33 million, Watts had sales of $181 million. [13] Leslie bought K&M Valve Company in 1995. [14]
