The globe valves, including
knife gate valves,Pressure Seal Globe ValveForged Steel Globe Valve, is a forced-sealed valve.
Under normal circumstances, the function of the shut-off valve is only
full opening and full closing, that is, the function of cutting off, but
some variants of the shut-off valve can also achieve adjustment and
throttling through some structural changes.The opening and closing
member used for the shut-off valve is a plug-shaped valve flap, which is
divided into a plane and a tapered surface on the sealing surface, and
the valve flap moves linearly along the center line of the fluid. The
movement of the valve stem has a lifting rod type and a lifting rotary
rod type.The stem axis of the globe valve is perpendicular to the seat
sealing surface. The medium flow direction of the globle valve is
changed from the valve flap to the valve chamber. At this time, under
the action of the medium pressure, the force to close the valve is
small, and the force of opening the valve is large, and the valve stem
opening or closing stroke is relatively short. Once the shut-off valve
is open, there is no longer any contact between its seat and the disc
sealing surface, so its sealing surface is less mechanically worn and
has a very reliable cutting action.The globe valve has simple structure,
high rigor, convenient manufacturing and maintenance, large water
resistance, and adjustable flow rate; “low-in and high-out” directional
when installed; mainly used in hot water supply and high-pressure steam
pipeline, not applicable A medium with particles and viscosity.We
produce all kinds of globe valves, including Bellows Seal Globe
Valve,Pressure Seal Globe Valve,Forged Steel Globe Valve which are
exported to the world and have a good market reputation. I hope to hear
from you.
