1) DESCRIPTION:
Gate valves are widely used for all types of applications and are suitable for both above ground and underground installation. Not least for underground installations it is paramount to choose the right type of valve to avoide high replacement costs.
Gate valves are designed for fully open or fully closed service.
They are installed in pipelines as isolating valves and should not
be used as control or regulating valves. Operation of a gate valve
is performed doing an either clockwise to close (CTC) or clockwise
to open (CTO) rotating motion of the stem. When operating the valve
stem, the gate moves up- or downwards on the threaded part of the
stem.
Gate valves are often used when minimum pressure loss and a free bore is needed. When fully open, a typical gate valve has no obstruction in the flow path resulting in a very low pressure loss, and this design makes it possible to use a pipe-cleaning pig. A gate valve is a multiturn valve meaning that the operation of the valve is done by means of a threaded stem. As the valve has to turn multiple times to go from open to closed position, the slow operation also prevents water hammer effects.
