Struggling with valve selection? Butterfly stem ball valve allows users to bid farewell to difficult choices
The Butterfly Handle Brass Ball Valve is a ball valve made of brass and operated with a butterfly handle. Rotating the ball opens or closes the pipeline, and it is mainly used in water, oil, and gas pipeline systems.
Product characteristics of butterfly valve
Pressure Resistance
The valve body is made of high-copper-content brass (HPb59-1), with a pressure resistance of ≤1.6MPa.
Low Leakage Rate
The valve core and seat are metal-fitted, with a leakage rate of ≤0.01% when closed.
High-Frequency Operating Life
The butterfly rod and valve core are integrally connected, supporting multiple opening and closing cycles per day, exceeding 10,000 times without loosening or jamming, suitable for public pipe networks and high-frequency applications.
Corrosion Resistance
The brass material is naturally resistant to water, air, and mildly corrosive media, requiring no additional anti-corrosion treatment and guaranteeing over 3 years without replacement.
Low Flow Resistance
The internal flow channel is continuous and wide, with a pressure drop of ≤0.05MPa (DN25 diameter water flow) when the valve is fully open, reducing pump energy consumption and system losses.
