Because the trim material of the section steel ball valve is carefully selected, the wall thickness of the valve body and the connection strength of the bolts of the valve body are in accordance with the requirements of the American standard ASMEB16.34. After rigorous calculations, the corresponding valve body pressure level and joint strength are ensured. Reliable strength. The sphere purchases a fixed structure and a floating valve seat, which can achieve a small torque under operating pressure. The valve body seal uses a metal sleeve with self-lubricating PTFE, which is matched with a high-strength, high-gloss valve stem to increase the friction coefficient Down to low.

The pipeline forged steel ball valve uses polymer material as the seat seal, and the seal seat is spring loaded. It has excellent sealing performance in a wide range of temperature and pressure changes, ensuring that no bubble leakage is achieved under the action of the closing pressure difference. Keep the operating torque small under large pressure differentials.

The design and manufacturing quality system of forged steel ball valves is based on the ISO9001 quality system standard and APIQI quality program specifications, and has been approved by DNV Classification Society and the American API Petroleum Institute respectively. It conforms to the ISO90001 quality system standard and conforms to the APIQ1 and API16D specifications. And authorized to use the API monogram, the certificate number is API6D-0652 The natural gas pipeline forged steel ball valve is a forged steel structure, especially suitable for gas, purified natural gas, sour natural gas, water, coal slurry and oil and other media working conditions, suitable for Class150 -Class1500, the working temperature is -28℃~300℃, on the pipeline of various working conditions such as petroleum, chemical industry, thermal power station, etc., it can cut off or connect the medium. Therefore, the pipeline forged steel ball valve has a variety of options, complete specifications and pressure levels, both full and contracted, and is an ideal valve for a wide range of applications in oil, natural gas, chemical raw materials and other transportation pipelines.
