Product Name: High-performance Pneumatic Butterfly Valve
Product Overview
Our high-performance pneumatic butterfly valves are specially designed for harsh industrial environments, achieving reliable shut-off and regulating control. This valve combines a meticulously designed butterfly valve body with an efficient and durable pneumatic actuator, providing rapid response and outstanding sealing performance for water, air, steam, various corrosive chemical media and slurries. Its robust structure, long service life and low maintenance requirements make it an ideal choice for modern industrial process automation.
Core features and advantages
Rapid response and efficient automation
The adoption of an optimally designed pneumatic actuator ensures that the valve can be opened and closed within seconds, significantly enhancing the efficiency of the process flow.
With the matching accessories such as solenoid valves and limit switches, it can be easily integrated into any automatic control system to achieve remote precise control.
Outstanding sealing performance
We offer a variety of valve seat sealing options (such as EPDM, NBR, FKM/Viton, PTFE), suitable for different temperatures, pressures and medium characteristics.
The precise butterfly plate design, combined with high-quality sealing materials, ensures an extremely low leakage rate and meets strict internal leakage standards.
Sturdy structure and long service life
Valve body: Made of high-quality materials (such as WCB carbon steel, CF8/304 stainless steel, CF8M/316 stainless steel), it features excellent corrosion resistance and mechanical strength.
Actuator: The cylinder is formed by extrusion of high-strength aluminum alloy and treated with hard anodizing, which is corrosion-resistant and wear-resistant. All moving parts are equipped with wear-resistant bushings, which greatly extends the service life.
Butterfly plate: Materials such as 304, 316 stainless steel or duplex steel can be selected according to the characteristics of the medium. The surface is often treated with coating or cladding to enhance wear resistance.
Flexible driving mode
Double-Acting type: It is used in situations where rapid opening and closing are required. The air source drives the actuator piston to move in both directions.
Single-acting spring-return type: In the event of a gas source failure or emergency, the built-in Spring can automatically drive the valve to the preset safe position (fully open or fully closed), ensuring system safety.
Low maintenance and easy installation
Modular design, easy to install, no special tools required.
The actuator does not require internal lubrication, reducing the complexity and cost of maintenance.
