Product Description

Professional Dn100 4 Inch WCB Lever /Gear Lug Type Butterfly Valve

The WCB Gear Lug Butterfly Valve is a valve that uses a disc or plate to control flow through a pipe. It is called a butterfly valve because the disc is shaped like a butterfly and rotates to open or close the valve.  WCB gear lug butterfly valves are made of WCB, which is a type of carbon steel. It has lugs or ears on the valve body and can be installed between the flanges of the piping system. The gear operator on the valve can be operated manually to open or close the valve, or it can be operated automatically using electric or pneumatic actuators. This type of valve is typically used in industrial applications where quick and easy flow control is required, such as water treatment plants, chemical processing plants, and oil and gas refineries.  WCB material adds to the valve's durability and corrosion resistance, making it suitable for harsh environments.
