This valve is particularly suitable where manual operation is impractical, where frequent valve cycling is required, or where remote operation and automation are integral to the process.
Related industrial valve products such as PTFE lined butterfly valves, pneumatic actuated butterfly valves, PTFE lined control valves, wafer type butterfly valves, and chemical process valves share overlapping application areas with this product. However, the Pneumatic PTFE Sleeve Butterfly Valve stands out due to its compact design, reliable pneumatic actuator, and full-bore flow characteristics, making it ideal for demanding Indian industrial operations.
ABOUT THE PRODUCT
A Pneumatic PTFE Sleeve Butterfly Valve is a quarter-turn rotary valve that uses a centrally mounted disc to control the flow of fluid. The disc rotates through a pneumatic actuator, which converts compressed air energy into mechanical motion. The internal sleeve, made from high-grade PTFE, isolates the valve body and disc from the process media, ensuring exceptional chemical compatibility and corrosion resistance.
Unlike conventional rubber-lined or metal-seated butterfly valves, the PTFE sleeve provides a non-reactive surface that can handle strong acids, alkalis, solvents, and corrosive chemicals commonly used in Indian process industries. The pneumatic actuation ensures uniform torque, repeatable positioning, and compatibility with automation systems such as PLCs, solenoid valves, and air preparation units.
Krishna Industries supplies Pneumatic PTFE Sleeve Butterfly Valves that are designed for wafer mounting between standard flanges. This compact mounting style reduces installation space, minimizes pipeline modifications, and lowers overall system cost while maintaining robust performance.
CONSTRUCTION DETAILS
Valve Body The valve body is typically manufactured from high-strength materials such as cast iron, ductile iron, carbon steel, or stainless steel, depending on application requirements. The body is designed to withstand pipeline pressure, mechanical stress, and Indian industrial operating conditions. The wafer-type construction ensures easy installation and alignment.
PTFE Sleeve The PTFE sleeve is the heart of the valve. It lines the entire internal flow path and provides a smooth, non-stick surface. PTFE offers outstanding resistance to a wide range of chemicals, high-purity fluids, and aggressive media. It also minimizes friction, reduces torque requirements, and enhances sealing performance.
Disc The disc is precision-machined and designed to provide accurate flow control and tight shut-off. Depending on application needs, discs can be manufactured from stainless steel or other compatible alloys. The disc profile ensures minimal pressure drop and efficient flow characteristics.
Shaft The shaft connects the disc to the pneumatic actuator. It is engineered for high strength, corrosion resistance, and precise alignment. Proper shaft sealing ensures leak-free operation and long service life.
Pneumatic Actuator The pneumatic actuator is a critical component that enables automated valve operation. It can be single-acting or double-acting, depending on control requirements. The actuator provides fast response, consistent torque output, and reliable operation even in demanding industrial environments.
End Connections The valve is designed for wafer-type installation between flanges, compatible with commonly used Indian piping standards. This design reduces weight and simplifies maintenance.
WORKING PRINCIPLE
The Pneumatic PTFE Sleeve Butterfly Valve operates on a simple quarter-turn mechanism. When compressed air is supplied to the pneumatic actuator, it generates rotational motion. This rotation is transmitted to the valve shaft, causing the disc to rotate.
When the disc is parallel to the flow direction, the valve is in the fully open position, allowing maximum flow with minimal pressure loss. When the disc rotates perpendicular to the flow, the valve closes, providing tight shut-off through contact between the disc and the PTFE sleeve.
The pneumatic actuator ensures smooth and controlled movement, making the valve suitable for frequent operation, remote control, and integration into automated process systems. In Indian plants where safety, consistency, and efficiency are critical, this working principle offers significant advantages over manual valves.
