PPH Pneumatic Actuated Butterfly Valve
A PPH Pneumatic Actuated Butterfly Valve is a type of valve made from Polypropylene Homopolymer (PPH) that uses a pneumatic actuator to control the opening and closing of the valve disc. It combines the chemical resistance of PPH with the automation and speed of pneumatic operation.Used for fast control and ON/ OFF operations and Size range from DN 40 up to DN 300 mm, series DIN 3202 K2 and ISO 5752 Medium series 25 and the working pressure 16 bar at 20° C to One piece body, and disc mate- rial: PVC-U. Their Oval holes body to fit with flanges in different standards
The valve body is made of PPH, which is highly resistant to corrosive chemicals, acids, and alkalis.The pneumatic actuator uses compressed air to rotate the valve disc either 90° (quarter-turn) for full open/close or partially for throttling.Also, controls the flow of liquids or gases in a pipeline and Provides fast, reliable, and remote operation compared to manual valves. They are widely used in chemical processing, water treatment, and industrial piping systems where automation and corrosion resistance are required.

Benefits of Using PPH Pneumatic Actuated Butterfly Valve
Corrosion Resistance
PPH (Polypropylene Homopolymer) material provides excellent resistance against strong chemicals, acids, and alkaline solutions, making it ideal for chemical and industrial applications.
Automated Operation
With pneumatic actuation, the valve can be operated remotely and automatically, reducing the need for manual intervention.
Fast Response
Pneumatic actuators allow quick opening and closing, which is useful for processes requiring rapid flow control.
Durability
PPH construction is lightweight yet strong, resistant to wear, and offers a long service life even in aggressive chemical environments.
Leak-tight Performance
Designed with precision seating, ensuring minimal leakage, which is crucial for hazardous or expensive fluids.
Low Maintenance
Fewer moving parts compared to other valve types reduce maintenance requirements.
Energy Efficiency
Pneumatic actuation can be more energy-efficient in automated systems compared to electric actuators for certain applications.
Compact Design
Butterfly valves have a slim, space-saving profile suitable for installations where space is limited.
Versatility
Suitable for on/off and throttling applications, handling liquids, gases, and slurries.
Temperature and Pressure Handling
Can operate in a moderate temperature and pressure range typical of chemical processing systems.
Types of PPH Pneumatic Actuated Butterfly Valve
Wafer Type
- Lightweight and compact.
- Installed between two flanges and held in place by flange bolts.
- Common for low to medium pressure systems.
Lug Type
- Has threaded inserts (lugs) on both sides of the valve body.
- Can be installed at the end of a pipeline or between flanges.
- Allows one-side removal of piping without disturbing the other side.
Double Flanged Type
- Flanged on both ends for secure bolting.
- Suitable for higher pressure and heavy-duty applications.
Triple Eccentric (High-Performance) Type
- Features an offset design that minimizes seat wear and improves sealing.
- Used for precise throttling and high-performance applications.
Spring Return vs. Double Acting Actuator
- Spring Return: Valve automatically returns to default position (open or closed) when air supply fails.
- Double Acting: Air is used for both opening and closing; no spring needed, ideal for precise control.
