The Pneumatic 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.

Using a new series of pneumatic actuators, there are double acting and single acting (spring return), gear transmission, safe and reliable; Large diameter valve adopts series AW type pneumatic actuator fork drive, reasonable structure, large output torque, double acting and single acting 1, pneumatic butterfly valve gear type double piston, output torque is large, small volume. 2, cylinder selection of aluminum gold material, light weight, beautiful appearance. 3. Manual operation mechanism can be installed at the top and bottom. 4, rack type connection can adjust the opening Angle, rated flow. 5, butterfly valve actuator can choose live signal feedback indication and various accessories to achieve automatic operation. 6. IS05211 standard connection provides convenience for the installation and replacement of the product. 7, both ends of the adjustable screw can make the standard product in 0° and 90° have a ±4° adjustable range. Ensure accurate synchronization with the valve.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.1. small and light, easy to disassemble and repair, and can be installed in any position. 2. simple structure, compact, small operating torque, 90° rotation open quickly. 3. the flow characteristics tend to be straight, good adjustment performance. 4.  the connection between the butterfly plate and the valve stem adopts a pin-free structure to overcome the possible internal leakage point. 5. the outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and extends the service life of the valve, and maintains zero leakage with pressure opening and closing more than 50,000 times. 6. the seal can be replaced, and the sealing is reliable to achieve two-way sealing.
