Motorized Three-Piece Ball ValveAdopting three-section structure valve body, matching with electric actuator, the valve body is compact and small, consisting of three parts of the valve shell, through four longer bolts from both ends to clamp the middle valve body and the valve ball and become. The advantage is that the middle part of the valve body can be taken out without dismantling the pipeline threads during maintenance and dismantling, and the four bolts can be dismantled directly. It is suitable for the occasions with small volume and narrow space in light industry machinery. It is characterized by small volume, simple supporting, and large circulation capacity. Especially suitable for the medium is viscous, containing particles, fiber nature of the occasion. Widely used in food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and research equipment, electric power and other industries in the industrial automatic control system.
Product Characteristics
- ball valvesIt is a three-piece structure, which is easy to install, dismantle and maintain.
- The valve body adopts precision silica-sol casting process with reasonable structure and beautiful modeling.
- The valve seat adopts elastic sealing structure, reliable sealing, easy opening and closing.
- The valve stem is a downward-mounted structure with inverted seals, so that the stem will not be washed out when the valve cavity is abnormally pressurized.
- The valves are available in threaded, welded and quick release connections with mounting platforms in accordance with ISO 5211.
