All valves are designed to stop, allow, or throttle the drift of a method fluid. Gate valves one of the authentic valve designs are ideally acceptable for on-off, especially liquid, service. A gate valve features by way of lifting a rectangular or round gate out of the direction of the fluid. When the valve is totally open, gate valves are full bore, that means there is nothing to hinder the drift due to the fact the gate and pipeline diameter have the identical opening. This bore diameter additionally determines the valve size. An gain of this fullbore plan is very low friction loss, which saves strength and reduces complete price of ownership.
