Product Features:
1.Corrosion Protection of Key Parts: Half lining butterfly valves use high-quality corrosion-resistant materials (such as, rubber, EPDM, NBR, etc.) to line the key parts of the valve seat and disc that are in direct contact with the medium, effectively preventing medium corrosion and ensuring stable operation of the valve under harsh working conditions.
2.Anti Blow-out Design: The unique valve stem design enhances the stability of the valve stem under high pressure environment, effectively preventing the valve stem from being blown out due to excessive internal pressure, ensuring safe and reliable operation of the valve.
3.Self-lubricating Shaft Sleeve: The ultra-low friction coefficient self-lubricating sleeve significantly reduces the friction resistance between the stem and the sleeve, making the butterfly valve open and close more smooth and effort-saving, while reducing wear and extending service life.
4.Bi-Directional Pressure Bearing Capacity: The bi-directional sealing design of half lining butterfly valve makes it keep excellent sealing performance whether under pressure from both positive and negative directions, which can meet the needs of various complex working conditions.
5.Flexible Valve Seat Options: Valve seat options are available in a variety of materials, including rubber, EPDM, NBR, etc. to meet the corrosion resistance and fireproof requirements of different medium and working conditions.
6.International Standard Top Flange: The ISO 5211 standard top flange ensures perfect connection with various actuators for easy integration and installation of automated control systems.
