Globe Valve
Product Description
Overview
1. The opening and closing member of the shut-off valve is a plug-type valve flap with a flat or tapered surface on the seal, and the valve flap moves linearly along the center line of the valve seat. The movement of the valve stem, as well as the lifting and rotating rod type, can be used to control the flow of air, water, steam, and various corrosive fluids.
2.Suitable for cutting, adjusting and throttling conditions. The valve stem has a relatively short opening or closing stroke and a reliable shut-off function. The change of the valve seat opening is proportional to the flap travel, which is suitable for adjusting the flow.
3. The electric stop valve is tight and reliable, and the sealing surface material is widely used in plastic, and the sealing property is good. It has also been widely used in vacuum systems.
4. It is easy to operate, and it can be opened and closed quickly. It only needs to be rotated 90° from full opening to full closing, which is convenient for remote control.
5. Easy maintenance, simple structure, the sealing ring is active, easy to disassemble and replace.
6. Wide range of applications, through a few millimeters, up to a few meters, high vacuum and high pressure conditions can be used.
