Single-acting Flange Butterfly Valve for Pneumatic Control

Flange connection Single-acting Flange Butterfly Valve

Single-acting Flange Butterfly Valve

Product Description:

The single-acting pneumatic flange centerline butterfly valve is driven by a single-acting pneumatic actuator to achieve rapid opening and closing of the valve. The flange connection method makes installation and maintenance more convenient. The center plate design optimizes the sealing performance of the valve, reduces the torque requirement during operation, and improves the operating efficiency and service life of the valve.

Technical features:

1. Single-acting pneumatic actuator: only the air source pressure is required to open the valve, and it automatically closes when the air is lost to ensure system safety.

2. Flange connection: provides a convenient pipeline connection method, easy to install and maintain.

3. Center plate design: optimizes fluid dynamics, reduces fluid resistance, and reduces operating torque.

4. Good sealing: high-quality sealing materials are used to ensure zero leakage in the closed state.

5. Fast opening and closing: pneumatic actuators provide fast response and shorten opening and closing time.

6. Wide range of application: suitable for a variety of media, including water, gas, oil, etc., especially suitable for occasions that require rapid cutting.
7. Corrosion resistance: Select appropriate materials according to the characteristics of the medium to ensure that the valve can work stably for a long time in harsh environments.

Product specifications:

- Nominal diameter: DN50-DN1200 (depending on the model)
- Nominal pressure: PN10/PN16/PN25, etc. (depending on the valve design)
- Applicable media: water, gas, oil and slightly corrosive media
- Working temperature: usually between -20℃ and +120℃ (depending on the material and seal)
- Control air pressure: usually 0.3-0.8MPa
- Ambient temperature: The working ambient temperature of the actuator is usually between -20℃ and +60℃
- Protection level: IP65 or higher, suitable for outdoor or dusty and humid environments
- Valve material: ductile iron, carbon steel, stainless steel, etc. (select according to the medium properties and working conditions).

Material & Size:

- Valve body material: ductile iron, carbon steel, stainless steel, etc.
- Sealing material: nitrile rubber (NBR), ethylene propylene diene monomer rubber (EPDM), fluororubber (FKM), etc.
- Connection method: flange connection, in line with international standards such as ISO, DIN, ANSI, etc.
- Size : customized according to specific models and requirements.

The above is the basic description, technical details and product specifications of the single-acting pneumatic flange centerline butterfly valve. This butterfly valve has been widely used in various industrial fields for its reliable performance and convenient operation. When selecting, it should be selected according to factors such as actual working conditions, media type, working pressure and temperature.
