Description
Flanged forged steel pressure seal globe valve is a type of flanged globe valve. It is mainly made up of valve body, disc, shaft pin and stem. This globe valve is a valve with closure member (disc) moving along with the center line with valve seat. Since it has relative short opening and closing stroke, this valve is very suitable for cutting off and regulating medium flow. All our products have passed CE and JB/T9092 certification.
Applications
Our flanged forged steel pressure seal globe valve is widely applied on tap water, sewage, building, petroleum, chemical, food, medicine, textile, electricity, ship, metallurgy, energy and other pipeline systems, such as
1. High temperature and pressure petrochemical pipelines systems in thermal power plants and nuclear power stations
2. Pipelines with small requirement on flow resistance (pressure loss)
3. Low requirement on regulating precision and small diameter (nominal diameter ≤ 50 mm) pipelines
4. Chemical fertilizer production line
5. Alumina production process (easy-coking pipeline in desilication workshop)
6. Water and heat supply engineering in urban construction
Features
1. The medium in the flanged forged steel pressure seal globe valve can only flow in one direction and the flowing direction can not be changed when the flanged globe valve is in operation.
2. When opened or closed, there is no relative sliding between valve body and disc.
3. Since medium channel twists and turns in valve body, the fluid resistance is big.
4. This flanged globe valve is featured by fine sealing performance and long service time.
5. Friction is small between sealing surfaces.
6. Precision casting technology is adopted to manufacture valve body.
7. CNC processing is applied on valve disc.
8. Two times shot blasting makes exquisite outward appearance of the flanged forged steel pressure seal globe valve.
