As these are not pilot-operated, they will incur a change in downstream pressure as the steam flow changes, and this should be taken into careful consideration when selecting and sizing the valve. This type of valve is installed with the actuator below the pipe when used with steam, and has a water seal pot to stop high steam temperatures from reaching and damaging the actuator’s flexible diaphragm, which is commonly made out of neoprene. A typical installation for the reduction of steam mains pressure is shown in Figure 7.3.3.

Larger capacity direct acting pressure reducing valves are also available for use on larger capacity plant, or on steam distribution mains. They differ slightly to the smaller capacity valves in that the actuator force is provided by pressure acting against a flexible diaphragm inside the actuator rather than a bellows.

So residential ones should be tested once a year. Another issue is that many T&Ps have drain lines that sometimes run through walls and outside. Those should always run generally down and out. If they go uphill anywhere, then water can pool at the valve if it opens and it may fail to work when needed. The example above is from our Closet of Horrors. What usually results in this is when an old tank had a top-mounted valve, but a new one was either shorter -- likely the case here -- or had a side-mounted valve, and rather than do it right, somebody just connected the old to the new.

Shinjo Company focuses on manufacturing valves and pumps, including ball valves, check valves, gate valves, globe valves, butterfly valves, safety valves, hydraulic control valves, pressure reducing valves, needle valves, cast steel valves and diaphragm pumps, split case pumps, centrifugal pumps, multistage pumps, submersible pumps, etc.

On the top or side of every tank heater, residential or commercial, sits a safety valve. Its purpose is to open and vent if the temperature or pressure inside the tank passes safe limits. Commercial ones are fairly robust, but about a quarter of residential ones fail every year.They should be tested once a year b

by pulling up on the handle. It should let water flow freely, and it should stop when you let go of the handle. Possibilities:

The valves have a thermostatic probe that needs to be in the heater, so the valve itself should be screwed directly into the tank and not have any other plumbing placed between it and the tank. If the pressure becomes too great, the worst that will happen is that the tank or piping springs a leak somewhere. But if the temperature becomes too great, the heater will explode like a bomb and quite possibly demolish everything nearby. Both Mythbusters and the Watts Regulator Co. (which makes T&P valves) have conducted tests, and where temperature goes past the limit, the tank flies hundreds of feet into the air and lands hundreds of feet away and destroys the little shed it was parked in.
