The Definox DMX PE/DMAX PE sampling diaphragm valve allows sampling to be carried out in optimal aseptic conditions. Its design incorporates a physical barrier between the interior of the valve and the external environment. Available in manual version (DMX PE) or in version with pneumatic actuator (DMAX PE). The latter can be fitted with a Sorio control top.

Maintenance document number : NM039

The Definox DPAX pneumatic butterfly valve is a shut-off valve. Efficient and hygienic in design, the DPAX allows fluid to pass without retention. Its patented seal technologies allow the DPAX to have quick maintenance and reduced OPEX costs. Easily convertible to NO or NC and equipped with a single-acting pneumatic actuator, the DPAX can be fitted with a SORIO control top.

Maintenance document number : NM222

The Definox DPAX EBC flanged pneumatic butterfly valve is a shut-off valve. Efficient and hygienic in design, the DPAX EBC allows fluid to pass without retention. Its design with compact flanges facilitates disassembly and maintenance operations. Added to its patented seal technologies, the DPAX EBC provides a reduced OPEX cost. Easily convertible to NO or NC and equipped with a single-acting pneumatic actuator, the DPAX EBC can be fitted with a SORIO control top.

The Definox DPAX DE pneumatically actuated butterfly valve is a double-seal mixproof valve with a leakage chamber. Based on a two independent butterfly discs design, it ensures optimal process safety and safe separation of incompatible fluids thanks to a monitored intermediate safety chamber.The leakage chamber enables rapid detection of any seal failure, while the intermediate space can be flushed and cleaned (CIP) to ensure a high level of hygiene. This design helps control the risk of cross-contamination in demanding process applications.

Standardized with the DPX / DPAX ranges, the DPAX DE uses common components, facilitating maintenance and spare parts management. Available with flanged connections only, it can be combined with DEFINOX detection solutions.

The AVX1 sanitary self-venting devices provide protection against vacuum and overpressure in inert tanks (sterile air or neutral gas). Their design ensures optimal cleaning of processes and equipment.

Maintenance document number : NM120

Actuators are available for individual purchase to enable modular component stocking or quick replacement during maintenance operations, without requiring full valve replacement.Repairable pneumatic actuator designed for DEFINOX DBAX series ball valves. The actuator is supplied with an integrated detection cam and a drive shaft enabling direct mounting onto the valve drive square.Depending on the selected configuration, the actuator can be delivered pre-equipped with a SORIO Basic wired control unit or SORIO control tops in wired, AS-i or IO-Link versions for valve position monitoring and control.


5-year manufacturer warranty, in accordance with the terms defined in the warranty document.

Handles are available for individual purchase to enable modular component stocking and quick replacement during maintenance operations, without requiring full valve replacement.The stainless steel trigger handle, lockable and multi-position, is designed for DEFINOX DPX and DPX EBC manual butterfly valves. Its multi-position system (5 intermediate positions + open / closed) ensures precise flow adjustment, while the padlock locking function secures the valve position during maintenance operations.The modular design ensures full interchangeability and allows quick handle replacement without removing the valve. The sleeve, available in several colors, facilitates process line identification.The handle can also be configured with position detection solutions: 0, 1 or 2 cylindrical M12 sensors for on/off detection or MVQ IO-Link rotary linear sensor enabling continuous valve position monitoring




A second handle version, called the micrometric handle, is also available. It provides an alternative enabling even finer operation and precise, repeatable valve position adjustment, particularly suited for applications requiring accurate flow control.

Maintenance document number : NM270

The NEOS double sealing is a shut-off valve with leak detection. It makes it possible to alert on a sealing failure thanks to its leak chamber, avoiding any risk of mixing. The NEOS can be equipped with an additional cleaning microvalve to flush the leak chamber. Robust and hygienic in design, its patented seal technologies allow the NEOS to have quick maintenance and reduced OPEX costs. Equipped with a single-acting pneumatic actuator (NO/NC), it can be fitted with a SORIO control top.
