A butterfly valve with flow control that has performance equivalent to JWWA B 138 standards.
It has performance equivalent to the JWWA B 138 standard butterfly valve, and by attaching a flow control plate with comb-like notches and numerous holes on the downstream side of the valve body, it disperses the water flow into fine jet streams, suppressing the occurrence and growth of cavitation. With low vibration and low noise, it enables "throttling operation," which was difficult with conventional butterfly valves, allowing for extensive flow control. 【Features】 - The flow control plate with comb-like notches and numerous holes disperses the water flow into fine jet streams, compensating for the negative pressure on the downstream side of the valve body and suppressing the occurrence and growth of cavitation. - Since the flow control plate can suppress the occurrence and growth of cavitation, cavitation characteristics are improved, making throttling operation possible, which was previously difficult with conventional butterfly valves. Additionally, the generated cavitation is finely dispersed, reducing the vibration and noise that occur during throttling operation, thus expanding the range of use. - The wetted areas on the inner surface are coated with a powder coating known to be resistant to cavitation, enhancing durability and also effectively addressing red water issues. - It is compatible with both vertical and horizontal orientations.
