The O Port valve, also called through-port valve has its basic advantage in the fact that the knife plate never leaves the hole, thus leaving no room for powder deposition. The moving plate has a hole in the middle which coincides with the port to give a full flow when open and offers a 100% shut off when closed.
Sizes from 80NB to 600NB as standard; Other sizes can also be made on request.
The valves are primarirly used for handling solids in flow media.
Best Suitable for Powders, without worrying about accumulation.
Proper actuation of the valve is guaranteed.
No material gets trapped in the bottom of the valve.
The valve has a class VI shut-off.
No Lubrication or Maintenance is required.
The valve can be used as shut-off valve, flow control valve and end of line.
Even in a partially open position the valve has a straight flow direction, unlike other valves.
Compact design, Short face to face dimension.
Foreign matter does not get jammed between the gate and the body. This prevents seat damage so that the valve always seats well.
Long leak free operation, through the valve and from the valve body.
The valves can be installed in any position in the pipe; they do not have a preferential flow direction.
