คำอธิบาย
J61H/Y American Standard วาล์วทรงกลมแบบเชื่อมปลาย
The J61H/Y American Standard butt-welded globe valve is designed for high-pressure
and high-temperature pipeline service. The valve is connected to the pipeline by
welding, providing a strong and reliable connection with excellent sealing
performance.
The optimized sealing surfaces are resistant to wear and scratching, which helps
extend the service life of the valve. Its compact construction, reliable opening
and closing performance, low overall height and convenient maintenance make it
suitable for water, steam and oil pipelines.
