NORTECH is one of the leading China Globe Valve Manufacturer & Supplier.

The shut-off valve refers to the word gate in which the closing piece (wide flap) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat port is proportional to the valve stroke. Since the opening or closing stroke of the valve stem of this type of valve is relatively short,
Moreover, it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, this type of shut-off valve is very suitable for use as a shut-off or adjustment and throttling.
The most obvious advantage of the globe valve is that in the process of opening and closing, the friction between the broad flap and the broad sealing surface is smaller than that of the gate valve, so it is wear-resistant. The opening height is generally only 1/4 of the diameter of the valve seat passage, so it is much smaller than the gate valve.
Usually there is only one sealing surface on the valve body and the valve disc of the stop valve, so the manufacturing process of the stop valve is relatively good, and the stop valve is easy to maintain. Nominal pressure or pressure level of the globe valve: PN1.0-16.0MPa, ANSI CLASS150-900, JIS
