A Pneumatic Operated Butterfly Valve is an advanced flow control solution designed for automated shut-off and throttling applications across various industrial sectors in India. By combining a robust butterfly valve body with a high-performance pneumatic actuator, this valve delivers fast response time, reliable sealing performance, and efficient operation in demanding process environments.
At Krishna Industries, Ahmedabad, Gujarat, India, we supply high-quality Pneumatic Operated Butterfly Valves engineered for long service life and consistent performance. As a prominent Supplier, Wholesaler, Exporter, Distributor and Trader, we serve industries across India with MOQ of 10 pieces and fast dispatch capabilities.
Comprehensive Introduction to Pneumatic Operated Butterfly Valves
Industrial fluid control systems increasingly demand automation for safety, accuracy, and productivity. The Pneumatic Operated Butterfly Valve is widely adopted due to its compact structure, lightweight design, and cost-efficient automation capabilities. It integrates a butterfly disc mounted on a rotating shaft and driven by a pneumatic actuator using compressed air.
Compared to manual valves, pneumatic automation ensures:
Rapid opening and closing cycles
Remote operation capability
Reduced manpower requirement
Improved process safety
Consistent torque delivery
This valve is often selected over alternatives like Wafer Butterfly Valve, Lug Type Butterfly Valve, Electric Actuated Butterfly Valve, Gear Operated Butterfly Valve, and Industrial Control Valve when compressed air systems are readily available and fast actuation is required.
Key Components of Pneumatic Operated Butterfly Valve
1. Valve Body
Available in Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), and Stainless Steel (SS304/SS316), depending on application requirements.
2. Disc
Precision-machined disc ensuring minimum pressure drop and efficient flow characteristics.
3. Seat
EPDM, NBR, PTFE, or Viton seats available based on temperature and media compatibility.
4. Pneumatic Actuator
Rack & pinion type actuator available in single acting (spring return) or double acting configuration.
5. Solenoid Valve & Accessories
Limit switch box
Air filter regulator
Positioner (optional)
Quick exhaust valve
Technical Specifications

Pressure Rating
PN10 / PN16 / Class 150
End Connections
Wafer Type
Lug Type
Flanged End
Operating Air Pressure
3 – 8 Bar compressed air
Temperature Range

Working Principle
The pneumatic actuator converts compressed air energy into mechanical rotational motion. When air pressure is supplied, the actuator rotates the shaft connected to the butterfly disc by 90 degrees, enabling the valve to open or close. In single acting actuators, spring return ensures fail-safe operation during air supply failure.
Double Acting Actuator
Air required for both opening and closing.
Single Acting (Spring Return)
Air for opening, spring force for closing (Fail-safe).
