Since 1993, Aira has focused on in-house valve manufacturing, application engineering, and process automation. Our Flush Bottom Ball Valves are available with manual or pneumatic operation to meet different plant and process control requirements.
Our range includes Full Bore and Reduced Bore Flush Bottom Ball Valves for pharmaceutical, chemical, food, biotech, and other process applications. Depending on the selected model and application, valves are available with multiple material, sealing, size, and operating options.
Choose from Aira’s Full Bore and Reduced Bore configurations according to your vessel design, required flow capacity, media, operating conditions, and discharge requirements.
Designed with a full bore flow path for applications requiring effective vessel discharge with minimal flow restriction. Suitable for selected reactor, filter dryer, vacuum dryer, pharmaceutical, chemical, and process applications.
A reduced bore configuration for tank and vessel-bottom applications where the process does not require a full-bore flow path. Available in a wider size range for different process and equipment requirements.
A Flush Bottom Ball Valve, also known as a Tank Bottom Ball Valve or Tank Flush Valve, is designed for installation at the bottom of tanks, reactors, and process vessels to control product discharge.
Its configuration helps minimize unwanted pockets and product retention around the vessel outlet while providing reliable isolation. Flush Bottom Ball Valves are commonly used in pharmaceutical, chemical, food, and other process industries where efficient vessel discharge and dependable shut-off are important.
Aira offers both Full Bore and Reduced Bore designs. The appropriate configuration depends on the required flow path, vessel design, media, size, and operating conditions.
| Feature | Full Bore Flush Bottom Ball Valve | Reduced Bore Flush Bottom Ball Valve |
|---|---|---|
| Flow Configuration | Full bore flow path | Reduced bore flow path |
| Size Range | 1½” to 6″ | 1½” to 14″ |
| Maximum Pressure | Up to 10 kg/cm² | Up to 10 kg/cm² |
| Maximum Temperature | Up to 250°C | Up to 180°C |
| Operation | Manual / Pneumatic | Manual / Pneumatic |
| Typical Use | Applications requiring a less-restricted discharge path | Applications where reduced bore is suitable |
Pressure and temperature suitability depends on the selected material, seat/seal arrangement, media, and actual operating conditions. Refer to the respective product specifications when selecting a valve.
Flush Bottom Ball Valves are primarily selected for equipment where process media needs to be discharged from the bottom of a tank or vessel while reducing areas where material can remain trapped.
Installed at vessel-bottom outlets to provide reliable isolation and controlled discharge of process media from reactors and processing vessels.
Flush Bottom Ball Valves can be used in suitable filter dryer and vacuum dryer systems where efficient product discharge and process isolation are required.
Suitable Flush Bottom Ball Valve configurations can support pharmaceutical and biotech processes where material compatibility, reliable shut-off, and reduced product retention are important considerations. For hygienic process lines requiring compact flow isolation, explore our Pharmaceutical Butterfly Valves.
Available stainless steel and sealing options allow the valve to be configured for compatible chemicals and different process conditions.
Flush bottom configurations can also be used for suitable food and general process applications involving tanks, mixers, and vessels.
Aira Flush Bottom Ball Valves are available with different configurations to meet specific vessel and process requirements.
Exact materials, sizes, pressure ratings, temperature limits, and sealing options vary between Full Bore and Reduced Bore models.

A Flush Bottom Ball Valve is used for controlling the discharge of process media from the bottom of tanks, reactors, dryers, and vessels. Its design helps reduce product retention around the vessel outlet while providing reliable isolation.
A Full Bore Flush Bottom Ball Valve provides a less-restricted flow path for discharge, while a Reduced Bore design has a smaller internal flow passage. Selection depends on the required flow capacity, vessel design, media, size, and process conditions.
Yes. Aira Flush Bottom Ball Valves are available with manual and pneumatic operating options depending on the model and application. Pneumatic configurations can be integrated with Aira Pneumatic Actuators for automated operation.
For pharmaceutical applications requiring controlled or modulating flow rather than simple isolation, a Pharmaceutical Control Valve can be selected according to the process media, pressure, temperature, flow requirements, and operating conditions. Aira offers pharmaceutical control valve solutions for suitable process and automation applications.
