International Compatibility / Bi-directional Sealing Full EPDM Lining / Dry Shaft Design Smaller Operating Torque / Easy installation & Maintenance Full bore feature International Compatibility TOP FLANGE: BV20 Series top flanges mounting meets ISO 5211 standard for direct mounting of Handles, Gear Operators, Pneumatic and Electric Actuators, no brackets are required, which allows of simple installation in the field, minimizes possible misalignment and reduces overall height. SIDE FLANGE: Connection compatibility design allows RBV010 Series Butterfly Valve to be installed between flanges of DIN PN 10/16, BS and ASME Class 150 simultaneously. Bi-Directional Sealing Concentric resilient seated design features the Series bi-directional bubble tight shut off with zero leakage. Bi-directional sealing breaks the directional limitation during installation ,making it much more flexible and more achieving friendly working. Zero leakage perfects the sealing performance especially in Gas and Air applications. Fully Lining Full EPDM lined valve interior completely isolating the line media from the body eliminating unnecessary contacts between media and body. Body material therefore does not have to be corrosion resistance materials, which usually being expensive, this feature lowers the overall cost. Dry Shaft Design Alternative to high corrosion resistance shaft materials the BV20 valves are equipped with the dry shaft provision .In that case the shaft with standard material is protected from the medium by applying rubber lining. This lining protects the standard shaft material against corrosive environments.
