ZFV Oil gas LUG triple offset butterfly valve. The valve shown in photo is casting carbon steel material ASTM A216 WCB with manual worm gear operation. 

As valve with flow controlling function, adjustable area of ZFV butterfly valve is almost from the 0 opening, until 90 degrees, the normal controlling performance is about 2 time more than general butterfly vlave . Control ratio is up to of 100: 1 or more. This is very important as a control valve, especially in large diameter pipeline. Since the cost of the globe valve is extremely high comparing the butterfly valve. In addition, the globe valve can not achieve zero leakage, in the need for emergency shutdown conditions, the other valve must be installed in the side of the closing valve, and ZFV valve can do include both control and shut down in one, the economic benefit is extremely impressive.
