DN500 Wafer Connection 10 Inch Stainless Steel Pneumatic Butterfly Valve
Our Advantages
Product Description
With simple structure, light weight, quick opening speed, pneumatic wafer switch butterfly valve consists of the piston type cylinder and the wafer type butterfly valve, and the spring return type valve can support automatic reposition function (air to open and close) when the air and power were cut off. This product is widely applied in the industrial pipeline fields of metallurgy, environmental protection, water treatment, petrochemical, powder.
The Characteristics of the products
★ The new technology for Direct Debugging Switch(DDS) in electric actuators
★ More than 50,000 operation life without fault, keep your system operating safely and reliably
★ The valve can complete the switch action in 4~7s
★ The newest driver technology of quick switch electric actuator makes the valves have no power consumption at idle time
★ Widely adaptability, various connection mode (flange type, wafer type, double plastic union etc. )
★ The ball valve is one of the least flow resistances in all valves, even reduced diameter ball valve, whose flow resistance is quite small.
