Gate Valve
The primary function of a gate valve is for creating isolation i.e. on or off. The secondary function of a gate valve can be for flow reduction - where the bore is tapered to be reduced bore. Gate valves should not be used for throttling (i.e. using the gate in any semi open / closed position) as this will result in erosion of the sealing surface. Gate valves which have been used for throttling will generally show a wear pattern on the bottom edge of the gate.
