Lug Type Butterfly Valve (Nickel Valve)

What is Lug Type Butterfly Valve?

Lug type butterfly valves; It performs the opening and closing process by rotating the discs made of nickel, stainless steel or different materials (AISI304, AISI316, AL-BR) fixed around a shaft in the center around that shaft. It performs the function of starting, slowing down or completely blocking the flow of liquid or gas by compressing the disc around the shaft with rubber or plastic gasket. It is the equipment used to stop, regulate or start the flow, which has a flap that can make a quarter turn around its own axis and a sealing gasket.

How Does the Lug Type Butterfly Valve Work?

Lug type butterfly valves have protruding lugs covering the entire body designed to accommodate the bolt holes in the flange to which it will be connected. butterfly valve type. It is mounted between two flanges by fixing with bolts, studs and nuts. This makes it impossible to disconnect only one side of the piping system from the valve. In addition to providing manual control, it is also suitable for use by mounting pneumatic actuators and electric actuators.

It is placed between the pipe flanges and the flange bolts surround the valve body. It is easy to install but cannot be used as an isolation valve. In addition to providing manual control, it is also suitable for use by mounting pneumatic actuator and electric actuator.
