Main advantages of the product
1. The key component of the American standard bellows gate valve is the metal bellows, which is automatically welded to the valve stem assembly at the lower end and the connecting plate at the upper end , forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem. 2. The double sealing design (bellows + packing) will prevent leakage if the bellows fails, and it meets international sealing standards. 3. The valve cover is equipped with a grease joint , which can directly lubricate the valve stem , nut and sleeve, unlike the traditional method of only adding lubricating oil to the thread. 4. The ergonomically designed handwheel has a longer service life, is easy and convenient to operate, and is safer and more reliable.
