Stainless Steel CF8 CF8M Flanged Globe Valve For Nitric Acid Corrosive Medium Pipeline Use
Product introduction:
Globe valve is a kind of cut-off valve, its sealing is by applying torque to the valve stem, the stem in the axial direction to apply pressure to the valve disc, so that the disc sealing face and seat sealing face tightly fit, prevent media leakage along the gap between the sealing face.
The sealing pair of globe valve consists of the disc sealing face and the seat sealing face. The stem drives the disc to move vertically along the center line of the seat.The opening height of the globe valve is small in the opening and closing process, which is easy to adjust the flow rate, convenient for manufacturing and maintenance, and wide applicable range of pressure.

Product features:
1. Globe valve with small friction between the sealing surface in the process of opening and closing;
2. Globe valve with low opening height, easy to manufacture and maintain.
3. Globe valve not only suitable for low pressure, but also suitable for high pressure.
4. The structure length of globe valve is larger than gate valve, meanwhile, the fluid resistance is large, and the sealing reliability is not strong in long-term operation.
