A ball valve engineered for auxiliary systems
The DBX/DBAX series completes the DEFINOX line for auxiliary circuits. The DBX is manually operated, while the DBAX is equipped with a pneumatic actuator. A Sorio control top can be added for control and position feedback. Full-port and reduced-port versions feature different effective bore diameters. Whether for a new installation or a retrofit, it is essential to review the actual bore size, weld connections, and required maintenance clearance. Count on VAMECA's local technical expertise to help you specify these components based on your media, operating conditions, and automation requirements.
Pneumatic Actuation
Automated operation with normally open, normally closed, or double-acting configurations to suit your operational requirements.
Two Bore Configurations
Full or reduced bore available to suit your specific flow rate, pressure drop, and effective diameter requirements.
Control and Signaling
Sorio control unit configured to operate the valve and transmit its status to the PLC.
Accessible Body
The design allows direct access to the valve body between the end connections, provided sufficient clearance is planned for maintenance.
Verify bore size and installation layout
The DBAX designation identifies a product family; on its own, it does not define the dimensions, end connections, or operator.
Available Configurations
Full Port
Available from DN 8 to DN 50. Recommended for applications where internal bore size is a critical selection criterion.
Reduced Bore
Available from DN 15 to DN 65. Compare internal diameter and flow requirements against the full-bore version.
DBX or DBAX
The DBX is manually operated via handle. The DBAX utilizes a removable pneumatic actuator and can be fitted with a Sorio control unit.
Technical Reference Points
Materials and End Connections
316L stainless steel and PTFE. Welded end connections available in SMS or DIN standards, configured to catalogue specifications.
Operating Conditions
The catalogue rates the product for a maximum pressure of 20 bar and temperature limits from -30 to 160 °C. Their simultaneous suitability must be verified for the intended service.
Internal finish
Standard internal surface finish is under Ra 3.2 µm, with a 0.8 µm finish available as a catalogue option.
Together, we review the valve, fail-safe position, and required control signals. This enables you to accurately define the configuration to order and identify the necessary interfaces to coordinate with your automation team.
OPERATION AND DOCUMENTATION
Integrate the valve into your automation system
Fail-safe position and available air quality are key factors in the selection process.
Set the fail-closed position
Specify whether the valve must fail open or fail closed upon loss of instrument air. This fail-safe requirement must align with the overall system design and process function.
Select the Expected Feedback
Identify your open/close feedback requirements and your facility's communication protocol. Sorio is notably available in digital, AS-i, or IO-Link configurations, depending on the model.
Ensure access to the valve body
Record the tag number and measure the clearance between adjacent equipment. Ensure the layout accounts for unobstructed access to seats and end connections.
