Advantages:
1. The double seal design of bellows and packing makes the stem seal much safer and more reliable, and meets the international sealing standards.
2. The valve adopts a cone seal, and no impurities on the sealing surface. When it tends to close, the sealing surface has self-cleaning effect. The conical sealing surface can amplify the stem axial force into a sealing force, which obtains a larger sealing pressure rate under the same pressure for easier close and better sealing performance.
4. All bellows are 100% low emission tested according to Class A in ISO15848 before delivery; All the bellow components and valves are 100% tested according to Class A in ISO15848 to ensure zero leakage.
5.The valve cover is equipped with a greasing joint, which can lubricate the stem, nut and Bush directly, unlike traditional gate valve,only lubrication for threads.
6. Ergonomics design handwheel, easy to operate.
Applicable medium: steam, hot and cold water, oil, biphenyl, fatty acid, etc.
