high pressure forged steel ball valve products overview :

 
High pressure forged steel ball valve is mainly used for long distance pipeline transportation of oil and natural gas and city gas pipeline system. Because of the characteristics of the valve used in long-distance pipeline, the ability to bear pipeline stress, weather resistance and long-term reliability are considered in the design; the sealing and structural design is unique to the special effects company. The operation modes of forged steel flange ball valve include manual worm gear drive, pneumatic, electric, pneumatic hydraulic linkage, electro-hydraulic linkage and other control forms.
 
The main features of high pressure forged steel ball valve are as follows:
 
1. Double cut-off and discharge. 2. Unzip. 3. Seal well. 4. Fire protection design. 5. Clean the pipeline. 6. Emergency seal. 7. High pressure valve. 8. Valve cover combination seal. 9. Sewage. 10. Extend the stem. 11. It can bear pipeline stress well.
 
Some forged steel high-pressure ball valve body is marked with an arrow. If there is no English fiow handwriting attached, it is the action direction of the seal seat, not as a reference for the flow direction of the medium, and the self discharge direction of the valve is opposite. In general, double seat sealed ball valves have two-way flow direction.
 
Fixed forged steel flange ball valve is suitable for class 150-600lb long-distance pipeline and general industrial pipeline with working temperature less than 150 ℃. The design of its harsh environment resistance has been comprehensively considered, and it is suitable for water, oil, steam and other media. Application of high pressure forged steel ball valve
 
1. When the stagnant pressure in the valve chamber exceeds the pre tightening force of the spring, the valve seat retreats away from the ball to achieve automatic pressure relief, and the valve seat automatically resets after pressure relief.
 
2. In case of fire or abnormal temperature rise, the valve seat sealing ring is burnt or softened. Under the action of spring and medium pressure, metal to metal contact is formed between the spherical part of the support ring and the ball, so as to achieve temporary sealing effect and prevent the further expansion of the fire, meeting the requirements of API 6fa.
 
3. The double sealing rings of ptfr packing and O-ring are used in the packing gland, which is suitable for gas medium. The packing is installed in the packing plate, and the new SF type self-lubricating sliding bushing with low friction system can be used to reduce the operating torque.
