Gate valves are used for on-off operation on hydrocarbon, general process and utilities service for all temperature ranges.
Their straight through configuration is typical of the sliding method of closure.
Forged gate valves are from ½" to 2" and wedge is solid type
Fast valves are over 2" and wedge is flexible
To avoid cavitation and flashing phenomenon trim parts are hardfaced with stellite n.6 .
