Available with L-Port and T-Port ball configurations, the Sanitary Pneumatic Square Three-Way Ball Valve can accommodate different flow-routing requirements. The stainless steel body, polished wetted surfaces, cavity-minimized seat structure, and pneumatic quarter-turn operation make it suitable for pharmaceutical, biotechnology, food, beverage, dairy, cosmetic, and other hygienic processing systems.
The L-Port ball connects two ports while isolating the third port. It is suitable when one process stream needs to be switched between two different pipelines, such as selecting between two tanks, transfer routes, or process outlets.
The T-Port ball provides more flexible communication between the three valve ports. Depending on the ball position, different pipelines can be connected or isolated, making it suitable for distribution, transfer, and multi-directional process routing.
The L-Port or T-Port configuration should be selected according to the actual pipeline arrangement and required switching positions. For complex systems, buyers can provide a process flow diagram so AVM can verify the required flow path before production.
The pneumatic actuator rotates the valve stem through 90° to change the position of the ball and redirect the process media. This quarter-turn mechanism provides straightforward switching between predefined flow paths.
The double-acting configuration uses compressed air for both opening and closing movement. It is suitable for automated systems where pneumatic control is required in both directions.
The spring-return configuration uses compressed air for one direction and spring force for the opposite movement. It can be selected when the process requires a defined default position after loss of air supply.
The pneumatic actuator can be combined with solenoid valves, limit switch boxes, positioners, and air filter regulators. These components allow the valve to be integrated with PLC or other process-control systems for remote switching.
The internal structure is designed to reduce unnecessary cavities around the ball and seat. This helps limit process-media retention during flow switching and supports hygienic operation where products are changed frequently.
The cavity-filled seat design reduces the available space around the sealing area where process residues could accumulate. This construction supports easier cleaning and helps reduce potential contamination points.
The standard internal surface finish is Ra ≤0.8 μm, with an optional Ra ≤0.4 μm electropolished finish. The smoother surface can reduce product adhesion and facilitate cleaning of the product-contact areas.
The Sanitary Pneumatic Square Three-Way Ball Valve is designed for integration into suitable CIP and SIP systems, allowing cleaning and sterilization procedures to be carried out while the valve remains installed. The actual CIP and SIP conditions should be checked against the selected seat and sealing materials.
AVM provides SUS304 and SUS316L stainless steel configurations. SUS316L can be selected for applications requiring higher corrosion resistance or more demanding product-contact conditions.
PTFE provides reliable sealing and chemical resistance for many compatible sanitary process applications. Its suitability should be confirmed according to the process medium, cleaning agents, and operating temperature.
EPDM and silicone can be selected for compatible sanitary processing applications according to the process medium, temperature, cleaning requirements, and sterilization conditions.
FKM is available for applications requiring suitable resistance to specific chemicals and operating conditions. Compatibility should be confirmed before selection.
The precision-machined ball and hygienic seat structure provide sealing between selected flow paths, helping prevent unwanted communication between isolated ports.
The elastic sealing structure allows the seat to accommodate normal changes in operating conditions, helping maintain contact between the ball and seat during repeated switching.
The precision-machined ball and seat are designed for smooth rotation with controlled operating torque, allowing the pneumatic actuator to operate the valve efficiently.
The 90° operating mechanism is suitable for process systems where flow paths need to be changed repeatedly during production, transfer, cleaning, or product changeover.
