National standard forged steel flange globe valve Product Overview:
National standard forged steel flange globe valve The overall flange valve has three valve cover design, the first is a bolt-type valve cover, through the concavity and convex surface connection, the use of stainless steel and flexible graphite spiral wound gasket, according to demand can also be used Ring connection, the second is a welded valve cover, welded by thread seal, according to demand can also be directly used rigid welding, the third is self-sealing valve cover, through the thread and self-sealing valve cover connection. Products are widely used in petroleum, chemical, pharmaceutical, power industry and other conditions on the pipeline.
National standard forged steel flange globe valve Features and Benefits:
◇ The product is designed and manufactured according to API 602 and BS 5352. The valve is positioned along the center for lifting movement (the bushing is made of special materials with good wear resistance and small friction coefficient). Flexible and reliable, excellent sealing performance. Products are widely used in petroleum, chemical, pharmaceutical, power industry and other conditions on the pipeline.
◇ hand wheel forging malleable forging, modeling with hand, the appropriate increase in friction, easy to open. And show a clear "open" and "l" and "mark". Larger caliber, higher pressure optional impact hand wheel.
◇ stem nut with high nickel ductile iron, and "t" r ... thread and stem with the transmission torque. The cover is covered with packing gland and press sleeve to ensure the concentricity of the stem. Reasonable packing letter to ensure that the valve is not leaked. Meet environmental requirements.
◇ The valve cover is provided with an upper sealing seat. In line with the requirements of the American Petroleum Institute API and the British BS standards.
