Our Advantages

Product Description
As one of the most common valves, the wafer type electric butterfly valve is suitable for the medium of water, oil and other liquid medium. The disc supports frame structure with high strength, large flow area, and small flow resistance. With whole baking finish surface, the valve can effectively prevent rusting, and is suited to different medium by changing high quality seal ring or seal material. The valves with two-way seal function can be installed in any direction and not be affected by the spatial position and the medium flow.

The Characteristics of the products
★GRAT new technology patent for Potentiometer Positioning Device(PPD)
★The new technology for Direct Debugging Switch(DDS) in electric actuators
★More than 100,000 operation life without fault, keep your system operating safely and reliably
★With simple and reliable working principle, the body can be installed in the least space
★Small pressure drops, Large flow capability
★Configured with a standard convex pipe flange, the body has high cost-effective, especially large diameter butterfly valve
★The flow characteristic is approximate to EQ%, and the same body can afford two kinds of function choices including switch action and modulation action.
