The Electric Actuator Control Butterfly Valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that is opened and closed with the circular butterfly plate rotating with the valve stem to realize the enabling action. It is mainly used as a cut-off valve, and can also be designed to have the function of regulating or breaking the valve and regulating. The butterfly valve is used more and more in low pressure large and medium diameter pipelines. Categories: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of the pneumatic butterfly valve are simple structure, small size and light weight, low cost, the characteristics of the pneumatic butterfly valve are especially significant, installed in the high-altitude tunnel, convenient operation through the two-position five-way solenoid valve control, and can also adjust the flow medium. Pneumatic adjustment butterfly valve is a valve (valve plate) revolving around a fixed axis perpendicular to the channel, which is composed of piston type double action or single action (spring return type) pneumatic actuator and butterfly valve, is a rotary high performance type adjustment or cut off valve class, with electric, gas valve positioner or solenoid valve, air filter pressure reducer, limit switch (valve position return), It can realize the proportional adjustment and two-position cut-off control of the fluid medium in the process pipeline, so as to achieve the automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.As a professional forged steel valve manufacturer and exporter, we promise to provide customers with high-quality after-sales service, including the following: 1.Provide product usage guidance and maintenance suggestions. 2.For failures caused by product quality problems, we promise to provide technical support and troubleshooting within the shortest possible time. 3.Except for damage caused by normal use, we provide free repair and replacement services. 4.We promise to respond quickly to customer service needs during the product warranty period. 5. We provide long-term technical support, online consulting and training services. Our goal is to provide customers with the best service experience and make customers' experience more pleasant and easy.1. easy operation: The operation of the electric butterfly valve is very simple, only need to press the button or use the remote control to control the switch and flow of the fluid medium. 2. high control accuracy: the device can accurately adjust the flow of the fluid medium and the opening and closing degree of the valve, so as to meet the flow control requirements under different working conditions. 3. easy maintenance: electric butterfly valve structure is simple, easy to clean and maintain, can effectively extend the service life. 4. energy saving and environmental protection: compared with the manual butterfly valve, the electric butterfly valve opens and closes more accurately, can achieve accurate flow control, to achieve the purpose of water saving, energy saving and material saving, and has played a positive role in environmental protection.

During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, it is wear-resistant. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
