Products Details

The welded ball valve with filter screen is a commonly used cut-off device in the fluid medium transmission pipeline, which is mainly used to remove impurities and dirt in the fluid medium and keep the transmission pipeline clean and smooth. The following is a detailed introduction of the welded ball valve with a filter screen:

Overview:
Welded ball valve with filter screen, such as GQ61F/GQ361F all-welded filter ball valve, is an effective and necessary cut-off device. It has the advantages of reasonable design, compact structure, flexible operation, easy installation and maintenance, significantly reducing the space occupied, which is conducive to reducing costs and widespread application.

Features:

Integral welded ball valve, no external leakage phenomenon.
The seat consists of a carbonized Teflon seal ring and spring, which is highly adaptable to pressure and temperature changes and does not produce any leakage within the standard pressure and temperature range.
The sealing ring is made of C-PTFE with 20% Carbon carbon to ensure no leakage.
The valve body, ball and side valve body are formed by seamless pipe pressing, and the valve stem is sealed by double-channel O-ring, and has the function of anti-blowout.
The filter and the ball are integrated into one, the filter ball valve is connected in the pipeline itself has a filtration function, can be used instead of the filter, play a multi-purpose effect of the valve, save the installation space and operating costs of the pipeline, can block the diameter of more than 4.5mm impurities through.

Part material table:

The material and design of the main components, such as the valve body, ball, edge valve body and cone valve body, ensure the durability and sealing of the valve.
Applications:
The all-welded ball valve combines the strength of light forgings with a compact ball/barrel design that complies with ISO17292 and API6D standards. Typically suitable for large diameter high-pressure lines, this series of ball valves has a unique design that provides maximum strength and reduces leakage points, while being the most resistant to pipeline pressure and stress. Temperature range from -46 to 220℃, all adopt fire protection design, and in accordance with API607 and API6FA fire test, through Lloyd's certification.
