The Sanitary Pneumatic Straight 3-Piece Ball Valve uses a full-bore flow passage to maintain efficient media transfer, while precision-polished product-contact surfaces help reduce residue retention and simplify cleaning. Manufactured from SUS304 or SUS316L stainless steel, it is suitable for hygienic applications in pharmaceutical, biotechnology, food, beverage, dairy, cosmetic, and fine chemical processing.
With pneumatic quarter-turn operation, the valve provides fast opening and closing for automated process systems and can be configured for CIP and SIP operations.
The three-piece construction allows the central valve section and end connections to be separated during maintenance. This provides easier access to internal components without replacing the complete valve assembly.
The ball, valve seats, and sealing components can be inspected and replaced when required. This makes the valve suitable for process lines where seals and seats are subject to repeated operating, cleaning, or sterilization cycles.
When wear occurs, maintenance personnel can service the internal components rather than replacing the entire pipeline connection. This can simplify spare-parts management and routine valve servicing.
The full-bore ball provides a flow passage that closely corresponds to the connected pipeline, allowing process media to pass through the valve with limited restriction when fully open.
The straight flow path minimizes unnecessary changes in flow direction, helping reduce pressure loss across the valve. This is useful for liquid transfer systems where maintaining available pump capacity is important.
A straight-through flow passage combined with polished wetted surfaces helps reduce areas where process media can accumulate after the valve is opened or closed.
The pneumatic actuator rotates the ball through 90 degrees. When the ball bore is aligned with the pipeline, the valve is open. Rotating the ball by 90 degrees positions the solid section across the flow path and closes the valve.
Quarter-turn operation provides rapid movement between open and closed positions, making the valve suitable for automated production sequences and frequent process switching.
Although this model is configured for pneumatic operation, AVM can provide manual or other actuation configurations according to system requirements.
The ball and seat structure is designed to reduce the torque required for operation, allowing the pneumatic actuator to provide reliable movement over repeated cycles.
SUS304 and SUS316L stainless steel are available for the valve body and ball. SUS316L can be selected for applications requiring greater corrosion resistance in demanding hygienic environments.
The standard surface finish is Ra ≤0.8 μm, with an optional Ra ≤0.4 μm finish for applications requiring a smoother internal surface.
The internal structure is designed to reduce dead zones and product retention, supporting hygienic operation and more effective cleaning.
The Sanitary Pneumatic Straight 3-Piece Ball Valve can be incorporated into CIP cleaning and SIP sterilization systems. The applicable cleaning and sterilization conditions should be confirmed according to the selected seat and sealing materials.
PTFE is available for applications requiring chemical resistance and stable sealing performance under suitable operating temperatures.
Silicone can be selected for compatible hygienic applications where flexibility and temperature performance are important.
EPDM is suitable for many water-based and general sanitary process applications and can be selected according to the process medium and cleaning conditions.
FKM can be selected for compatible applications requiring resistance to certain chemicals and higher-temperature process conditions.

Tri-Clamp connections allow relatively quick installation and disassembly and are suitable for sanitary process systems requiring regular inspection or maintenance.
Butt-welded connections provide a permanent connection with fewer detachable joints and are suitable for hygienic pipeline systems where internal smoothness is important.
Threaded configurations provide a convenient connection option for compatible process equipment and piping systems.
Flanged connections can be used where the valve needs to interface with compatible equipment or piping systems using bolted connections.
The pneumatic actuator provides automatic quarter-turn operation and can be integrated into process automation systems.
A solenoid valve can be used to control the actuator's air supply based on electrical control signals from the plant automation system.
Position feedback accessories can be added where the PLC or control system needs confirmation of the valve's open or closed state.
An air filter regulator can be incorporated into the pneumatic circuit to help provide appropriately conditioned compressed air for stable actuator operation.
The Sanitary Pneumatic Straight 3-Piece Ball Valve can be used in pharmaceutical and bioprocessing systems for compatible applications such as purified water, WFI, sterile liquid transfer, vaccine production, bioprocessing equipment, and CIP/SIP systems.
Typical applications include milk, yogurt, dairy ingredients, sauces, edible oils, and other compatible liquid food processing systems where hygienic flow isolation is required.
The full-bore configuration can be used in beer, soft drink, juice, and other beverage production lines where efficient liquid transfer and automated shut-off are required.
The valve is suitable for compatible production systems handling shampoo, lotion, cream, and cosmetic ingredients where cleanability and process control are important.
For compatible fine chemical, high-purity water, laboratory, and other cleanliness-sensitive applications, the stainless steel construction and polished flow path provide controlled fluid handling.
If the process requires frequent inspection or replacement of valve seats and seals, the three-piece construction provides easier access to the internal components.
Confirm the process liquid or gas before selecting SUS304 or SUS316L and the appropriate seat and seal material.
The standard working pressure range is 1.0–1.6 MPa, while the operating temperature can reach -20°C to +150°C depending on the selected seat material.
Ra ≤0.8 μm is the standard finish. Applications with stricter surface requirements can specify the optional Ra ≤0.4 μm finish.
Confirm the required connection and applicable standard before ordering, particularly when replacing an existing sanitary valve.
For automated systems, confirm the pneumatic actuator configuration and whether solenoid valves, position feedback, or other control accessories are required.
The standard production lead time is 2–4 weeks, depending on order quantity, specifications, and material availability. Urgent orders should be confirmed with AVM before purchase.
Standard payment terms are 30% deposit with the remaining 70% paid before shipment by T/T or L/C. Small-value orders may require full payment before production.
The valves are securely packed in suitable paper and wooden cases to reduce the risk of damage during handling and international transportation.
The main advantage is maintenance accessibility. The three-piece body allows the central valve section to be separated so internal components can be inspected or replaced more conveniently.
A 3-piece design provides greater access to internal components for maintenance, while a 2-piece design generally provides a simpler and more compact body construction.
Yes. The valve uses a full-bore ball design to provide a relatively unrestricted flow passage and reduce pressure loss when fully open.
Yes. The sanitary construction supports integration into CIP and SIP processes. Actual cleaning and sterilization parameters should be confirmed based on the selected seat and seal materials.
The valve body and ball are available in SUS304 or SUS316L stainless steel, with PTFE, Silicone, EPDM, and FKM sealing options.
The specified working pressure is 1.0–1.6 MPa. The exact pressure rating should be confirmed according to the selected size and configuration.
