The electric butterfly valve uses electric energy as the driving force, and the valve stem is driven by the electric device to make the butterfly plate produce a 90° rotation to achieve the opening and closing of the valve.
You can actuate butterfly valves using various methods: Manual: Using handwheels or levers. Electric: Using an electric motor, often controlled by a 4-20mA signal. Pneumatic: Using compressed air for high precision control. Hydraulic: Ideal for applications requiring large torques, such as high-pressure and high-viscosity fluid control.
Electric actuators use an electric motor to turn the butterfly valve stem. This method is suitable for applications that require high precision. It’s also ideal for situations where time-sensitive control is important. Electric actuators are typically controlled by a 4-20mA signal, allowing precise regulation of the valve’s position.
Lug butterfly valves have threaded inserts on the valve body, allowing them to be bolted to the pipeline on both sides, enabling installation without shutting down the entire system. The double offset design features an eccentric disc and offset stem, reducing friction and improving sealing performance.
In the world of industrial valves, the butterfly valve stands as a versatile and widely used component, playing a pivotal role in controlling the flow of fluids in various applications. Its unique design and efficient operation have earned it a significant place in industries ranging from water treatment and power generation to oil and gas.
When selecting an actuation method for a butterfly valve, several factors should be considered: Frequency of Use: Manual actuation is best for valves used infrequently. For frequent use, automated methods like electric, pneumatic, or hydraulic actuation are more suitable.
