WITT Gas Controls will exhibit at FABTECH 2026, scheduled for October 21-23 at the Las Vegas Convention Center in Las Vegas, Nevada. The company, which describes itself as a global leader in gas safety, control and analysis solutions, invites attendees to Booth S46114 to discuss its MEM+ gas mixers, dome pressure regulators and gas safety valves. The focus is on precise mixing, stable pressure and system protection.
Fast, accurate gas blending
The MEM+ series is designed for precise blending of two or three non-flammable gases, including nitrogen, carbon dioxide and oxygen, across a range of industrial applications. According to WITT, electronically operated, motorized proportional valves allow adjustments in 0.1 percent increments. The system can achieve the desired gas mixture in less than three seconds, with accuracy better than ±1% absolute.
Seven interface options, including Ethernet, OPC UA and PROFINET, support integration into existing systems. Users can operate the mixers remotely through a PC, PLC or machine controller, or directly through an intuitive touchscreen interface. This combination gives operators both local access and a route into plant-level control and automation architectures.
Pressure equalization is intended to compensate for supply pressure fluctuations. Continuous inlet pressure monitoring and pressure alarms support safe, reliable operation, while an integrated buffer tank accommodates fluctuating flow rates. The MEM+ series is housed in a splash-proof, brushed stainless steel enclosure and supports maximum inlet pressures of 20 bar and maximum outlet pressures of 10 bar.
- Gas service: two or three non-flammable gases, such as nitrogen, carbon dioxide or oxygen
- Adjustment: motorized proportional valves in 0.1 percent increments
- Response: desired mixture in less than three seconds
- Accuracy: better than ±1% absolute
- Interfaces: seven options, including Ethernet, OPC UA and PROFINET
- Pressure limits: 20 bar inlet; 10 bar outlet
Pressure regulation and retrofits
WITT will also highlight dome pressure regulators built with optimized pilot pressure regulators. These are designed to maintain stable working pressure as flow rates and inlet pressures change, supporting consistent process performance and product quality, the company says. The improvements can also be retrofitted to existing WITT dome pressure regulators without replacing the entire system.
Protection against backflow and overpressure
The company will also feature ULTRA non-return valves and ULTRAVENT safety relief valves. ULTRA non-return valves combine low opening pressures, tight sealing and minimal flow resistance to help protect gas systems from unwanted backflow. ULTRAVENT safety relief valves are intended to protect against excessive pressure and respond to pressure increases as low as 5 mbar.
For FABTECH visitors, the combined exhibit presents three areas of gas-system control: blending accuracy, pressure stability and component-level protection. The products are presented as part of an integrated approach to industrial gas handling, with specifications and interface options intended to help users adapt systems to different process and control requirements.
