stop valves, and at the same time, give check valve protection in the event of fluid back flow. Edward stop-check valves are commonly used to prevent back flow from a header fed from two or more sources when there is a loss of pressure in one of the sources — for example, the boiler outlet to a common header or at the feedwater heater outlets.

1992年2月24日 · in a separate control pilot. This type of valve uses the line pressure through the control pilot to the piston in the main relief valve and thereby maintains a high degree of tightness, especially as the set pressure is being approached. Another feature of the pilot-operated valve is that it will permit a blowdown as low as 2 %.

A.D. 39). This type of valve continued to be used with little variation until the advent of steam as a motive power, when the screw-down stop valve and weight-loaded safety valve were developed. The apparent absence of progress in valve design for two thousand years is obviously due to the fact that man had not yet appreciated the uses of

2. The water feed line piping, valves, and fittings from the required check valve to the feed pump shall have a pressure rating of not less than the pressure required to feed the Boiler but never less than 100 PSI.
