Shut-off valve

Close to the perpendicular to the axis of the valve seat sealing surface of the valve stem. System opening or closing stroke is relatively short, and having a very reliable interface makes this valve is suitable as a medium cutting or throttle.
A valve shut-off valve in the open position is no longer contact between the valve seat and valve sealing surface, and having a highly reliable cutting operation, and connected to said valve portion, or as a medium suitable for the flow rate adjustment section.high temperature solenoid valve
As long as the valve is opened, the seat and the valve sealing surface is no longer in contact, so there is less mechanical wear of the sealing surface of a relatively simple, because the most of the valve seat of the valve opening and shutting, in order to remove and repair or replacement The sealing element, there is no welding of pipes, valves and piping from the whole valve Occasion one is very suitable. The change in direction of flow of the medium, so that the valve, the flow resistance and thus the higher the valve shut-off valve.
Top shut-off valve are the following: 1) the angle stop valves, angle valves, simply by the direction of the liquid, so that the pressure drop through the valve, the valve than the conventional structure. 2) The DC cut-off valve, in co-or Y-shaped cut-off valve, wherein said flow channel and the runner to slash the valve mechanism, the extent of damage in this stream state is less than the traditional cut-off valve, and therefore also the pressure drop across the valve is small. 3): This form of one-way valve is a variant of the conventional globe valve piston valve. The valve and the valve seat in the valve, usually on the piston principle. A valve, which is the the elastic ring piston and piston and stem seal polishing. Separated by two elastic sealing ring collar and the valve piston pressure created detention resilient sealing valve cover gasket loading nut may be replaced by a variety of materials may also be used, the valve is substantially in the "on" or "from" use, but a special form of a piston or a lot of the collar, but also can be used to regulate the flow.two position three way valve
