Purpose and features:
The BR.W73E series three eccentric high-performance sealing butterfly valve has a unique three-dimensional eccentric structure and good shut-off performance. It is a new type of regulating valve that combines both regulation and shut-off functions, with a compact structure, simple flow path, low pressure loss, and high rated flow coefficient, can effectively meet various working conditions and requirements. It is widely used in fluid regulation in industrial automation control applications.
Features:
1. The sealing surfaces of the valve disc and valve seat are in conical contact, and the torque when the valve is closed is small, allowing for a large pressure difference;
2. The sealing surface can be welded with Stellite alloy for high-temperature and high-pressure applications;
3. With bidirectional sealing characteristics, the sealing performance is not affected by temperature changes;
4. Good sealing performance, reaching Class VI leakage (GB/T4213-2008).
