Features
1、Compact Structure, High Strength: The two-piece body construction with a square external shape not only enhances the overall torsional and bending strength of the valve, resisting pipeline stresses, but also results in a compact, lightweight design, facilitating installation and maintenance in space-constrained locations.
2、Reliable Connection, Leak-Free: The valve utilizes a socket weld connection, strictly complying with standards such as ASME B16.11. Welding creates a permanent connection between the valve and the pipeline, fundamentally eliminating potential leak points at the joint. This is particularly suitable for severe service conditions involving high temperatures, high pressures, and strict leakage requirements.
3、Excellent Sealing Performance: The ball and seat sealing surfaces are precision-machined. The ball surface typically undergoes hardening treatments such as hard chrome plating or nickel-based alloy coating. Seats are made from materials like reinforced PTFE or PPL, ensuring low operating torque, reliable sealing, and achieving zero-leakage shut-off of the media.
4、Safe and Reliable Operation: The stem features an anti-blowout design. Combined with V-shaped PTFE or flexible graphite packing, it forms a reliable multi-stage sealing system that effectively prevents external media leakage. The square handle design not only requires low operating torque and provides a comfortable grip but also clearly indicates the valve's open/closed status.
5、Wide Applicability: The body and key internal components can be manufactured from corrosion-resistant materials such as high-quality forged steel, forged stainless steel, depending on the service conditions. It is widely used in pipelines across industries like petroleum, chemical, natural gas, power generation, and metallurgy for isolating or connecting media such as water, steam, oil, and corrosive fluids. It is an indispensable control component in high-integrity piping systems.
6、Economical and Convenient Maintenance: The two-piece construction allows for valve maintenance without complete removal from the pipeline. Only a portion of the body needs to be disassembled to access the ball and seat for cleaning or replacement, significantly reducing maintenance costs and downtime.
