Basic info
- CF8 seat: stainless steel is welded to the body to a smooth circle, it can bear the corrosive environment, so it is suitable for a wide range of industrial applications
- Airtight seal: the top check method of sealing test, avoid for any signs of leakage, such as hissing sounds, visible leaks, or pressure drop.
- Long life: cf8 material has excellent durability and can withstand long-term use and high pressure conditions, reducing the frequency of maintenance and replacement.
- A non-rising stem design of gate valve, the non rising stem gate valve can save space compared with rising stem gate valve.
- They are commonly used in applications of Petroleum, chemical, electric power, metallurgy and other industries, where a straight-line flow of fluid and minimum restriction is desired.
