The direct actuator mounting simplifies automation and maintenance.

Versatile Industrial Applications

Ideal for environments requiring precise, automated flow control, the valve supports media like chemicals, water, air, and oils. Its multiple seat and disc combinations, wide temperature range, and full port capacity make it a preferred solution for manufacturers, fabricators, and suppliers across India.

Flexible Design and Standards Compliance

With connection types including wafer, lugged, and flanged, the valve fits diverse piping systems. It conforms to ISO 5211 and EN 593, ensuring interchangeable installation. The mounting pattern and air inlet specifications provide compatibility with standard pneumatic automation setups.

FAQ's of Pneumatic Butterfly Valve:

Q: How does the pneumatic butterfly valve achieve bubble-tight shutoff?

A: The valve uses high-quality seats such as EPDM, PTFE, NBR, or Viton and a precision-engineered disc to ensure bubble-tight Class VI shutoff, preventing any leakage even under demanding operating conditions.

Q: What is the benefit of using different disc and seat materials in this valve?

A: Choosing disc materials like stainless steel, ductile iron, or nylon coated, and seats such as EPDM, PTFE, NBR, or Viton, allows compatibility with various fluid media, enhancing corrosion resistance, longevity, and performance based on specific process requirements.

Q: When should a single acting actuator be chosen over a double acting type?

A: A single acting pneumatic actuator is preferred when failsafe closure is necessary in emergency situations, as it uses spring return, while double acting actuators are ideal where bi-directional control and greater torque are required.

Q: Where can this pneumatic butterfly valve be installed?

A: The valve is suitable for installations in industrial automation systems, chemical processing plants, water treatment facilities, and any application requiring precise flow control for liquids or gases, across piping sizes 2 to 16 inches.

Q: What is the typical process for mounting the actuator on this valve?

A: The actuator mounts directly to the valve following ISO 5211 pattern dimensions, ensuring easy, secure attachment without the need for additional adapter plates. This streamlines installation and maintenance.

Q: How does the visual or mechanical position indicator support valve operation?

A: A position indicator provides immediate feedback on valve status, enhancing operational safety and allowing operators to monitor open or closed positions during remote or automated control sequences.

Q: What advantages does full port capacity offer in industrial usage?

A: Full port design ensures minimal flow restriction, enabling efficient fluid handling and reducing energy consumption, especially in processes where maintaining high throughput and consistent pressure is critical.
