شیر پروانه ای سه فاز 4 اینچی 150 پوندی

The 4" 150LB triple offset butterfly valve is widely used in applications requiring tight shut-off, low leakage, and reliable performance under moderate pressure conditions. Thanks to its triple offset design, the valve eliminates friction between the disc and seat during operation, reducing wear and extending service life. This makes it ideal for frequent cycling and critical isolation in industries such as oil and gas, chemical processing, power generation, and HVAC systems. The 150LB rating ensures it operates effectively in systems with lower to moderate pressure levels, while the compact 4-inch size is suitable for mid-scale pipelines or equipment connections. The metal-to-metal sealing provides excellent resistance to high temperatures and corrosive media, making it suitable for both liquid and gas flow control. With precise shut-off capability and minimal maintenance requirements, this valve offers high reliability and efficiency for industrial flow management.
