Types of Manual Valves. Many different types of manual valves are used in industrial applications worldwide. The following article will cover the general mechanism and function of the most typical of these valves used in steam systems, such as ball valves, butterfly valves, globe valves, gate valves, and diaphragm valves. According to JIS, a valve is defined as:
Most steam traps are nothing more than automatic valves. They open, close or modulate automatically. The three important functions of steam traps are: 1  Discharge condensate as soon as it is formed.(Unless it is desirable to use the sensible heat of the liquid condensate).2  Have a negligible steam consumption.(i.e. being energy efficient). 3  Have the capability of discharging air and other non-condensable gases., the center view, Fig. 2, shows the cardinal feature of this trap, that it contains a collector for silt, sand, or sediment which is not, as in most other traps of the time, carried out through the valve with the efflux of water.
