ANSI Bellows Seal Gate Valve
Main advantages of the product:
1.Bellows sealed gate valve, the key component of which is metal bellows, adopts automatic roll welding at its lower end and valve stem assembly, and automatic roll welding at its upper end and connecting plate, forming a metal barrier between fluid medium and atmosphere to ensure zero leakage of valve stem.
2.The valve has double sealing design (both bellows and packing). If bellows fails, valve stem packing will also avoid leakage and conform to international sealing standards.
3.The bonnet is provided with a greasing joint, which can directly lubricate the valve stem, nut and shaft sleeve, unlike the traditional method of only adding oil to threads.
4.Ergonomically designed handwheel has longer service life, easy and convenient operation, and is safer and more reliable.
