Globe Valve Good Sealing, Small Friction Between Sealing Surfaces, Long Life
Nov 03, 2017

The stem axis of the globe valve is perpendicular to the seating seal surface, valve stem opening or closing stroke is relatively short, the valve disc once in the open condition, its valve seat and disc sealing surface between the no longer contact, and has a very reliable cutting action, making the cut-off valve products suitable as a medium for cutting or regulating and throttling use. Once the cut-off valve is in the open state, the valve seat and disc sealing surface between the no longer contact, so the cut-off valve sealing surface mechanical wear less. Since most of the valve seats and discs are easier to repair or replace the seals without having to remove the entire valve from the pipeline, this is a good fit for the welding of valves and pipelines. The flow direction of the medium through such valves has changed, so the flow resistance of the cut-off valve is higher than that of other valves.

Cut-off valve, also known as Jummen, is a widely used valve, it is widely popular, because of the opening and closing process of friction between the small, more durable, open high, easy to manufacture, easy to maintain, not only applicable to the medium and low pressure, but also applicable to high pressure.

Closing valve closed principle is to rely on the pressure of the valve, so that the disc sealing surface and valve seat sealing surface closely fit to prevent media circulation. The cut-off valve only one-way flow of media, the installation of directional. The structure length of the cut-off valve is larger than the gate valve, while the fluid resistance is large and the sealing reliability is not strong in the long run.

Cut-off valve Use method:

The valve stem axis of the globe valve is perpendicular to the seating seal surface. The valve stem opens or closes the stroke relatively short, and has the very reliable cut movement, causes this kind of instrument valve to be suitable as the medium the cut-off or the adjustment and the throttling use.

Once the disc of the globe valve is in the open condition, the valve seat and the disc seal face are no longer contact, and have a very reliable cutting action, the instrument valve is very suitable as a medium for cutting or regulating and throttling use.

In addition, the cut-off valve once in the open state, its valve seat and disc sealing surface is no longer contact, so its sealing surface mechanical wear less, because most of the valve seat and disc easier to repair or replace the seal components without the entire instrument valve removed from the pipeline, This is very suitable for the instrument valve and the pipeline welding into one occasion.
