Product Description
A butterfly valve actuator controls the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in only one direction.
Butterfly valves are often distinguished by the three main types: zero, double, or triple offset.
- Zero Offset Butterfly Valves.
- Double Offset Butterfly Valves.
- Triple offset butterfly valves.
Reliable Shutoff PerformanceAchieve 100% tight shutoff with the PTFE Butterfly Valve, which features a bubble-tight sealing capability and is designed for low torque operation. The combination of PTFE and EPDM or Viton backup ensures excellent resistance to aggressive media, with mechanical visual indicators for secure and visible valve positioning.
Versatile Application and Easy InstallationSuitable for double flanged installation in process lines, the valve is ideal for chemical, pharmaceutical, food, and water treatment sectors. Its ISO 5211 mounting pad and flanged ends compatible with DIN, ANSI, and JIS standards make it easy to integrate into various systems, while its customizable dimensions meet specific process requirements.
Enhanced Safety and Low MaintenanceThis valve features a spring return mechanism for fail-safe operation and manual override for added control during emergencies. The epoxy powder-coated body and streamlined disc design reduce torque, minimize wear, and facilitate effortless maintenance, cleaning, and replacement, ensuring long-term reliability.
FAQ's of PTFE Butterfly Valve With Pneumatic:
Q: How does the PTFE Butterfly Valve with Pneumatic Actuator ensure leak-free operation?
A: The valve uses a PTFE sealing material with EPDM or Viton backup, achieving bubble-tight shutoff and 100% leakage prevention, even under challenging media conditions. Compliance with API 609 leakage class ensures reliable performance.
Q: What industries commonly use this butterfly valve?
A: Chemical, pharmaceutical, food processing, and water treatment industries utilize this valve due to its resistance to corrosive fluids, gases, water, and slurries, along with its adaptable connection options and robust performance.
Q: Where can this valve be installed, and what are the connection options available?
A: This valve is suitable for double flanged installations and can be connected via wafer, lug, or flanged types compatible with DIN, ANSI, or JIS standards, providing flexibility for new setups and retrofits across various processing plants.
Q: How is maintenance performed and what are its advantages?
A: Maintenance is straightforward thanks to the valve's design for easy cleaning and replacement. The streamlined disc profile and stainless steel components minimize wear, reducing the frequency and complexity of service.
Q: What safety features are included in this valve design?
A: Safety features include a spring return mechanism for fail-safe automatic closure and a manual override option for operational control in the event of actuator failure, ensuring maximum process safety.
Q: When should you choose a double or single acting actuator setup?
A: Single acting (spring return) actuators provide fail-safe operation in critical processes where automatic closure is required during system failures, while double acting actuators are preferred when both opening and closing require pneumatic control.
Q: What benefits does the streamlined disc design offer in operation?
A: The streamlined disc profile is engineered to result in lower torque output, providing smoother operation and improved energy efficiency while prolonging actuator and valve life.
