WITT presents its revolutionary ULTRAVENT series- innovative millibar valves for precise pressure control from 5 to 500 mbar. These highly versatile valves reliably regulate both negative and positive pressure and ensure maximum control and safety in systems, vessels and production processes. ULTRAVENT valves are true allrounders. They function as safety relief valves, control valves, vacuum breakers, overflow valves, pressure relief |
valves, tank breather valves, venting valves and even as an alternative to bursting discs. As a purely mechanical solution, the spring-loaded components are particularly uncomplicated and at the same time highly precise and reliable. If the set pressure is exceeded, the precision valves open and automatically close tightly again after pressure equalisation. The model range has been tested over 100,000 cycles to ensure maximum reliability. |
ULTRAVENT is the only valve of this type with TÜV Type Approval as a safety valve in the pressure range 100 to 500 mbar, per DIN EN ISO 4126-1. Its flow-optimised design allows very high flow rates when required, despite its compact size. Thanks to its high-quality elastomer seals, the valves also feature extremely low leak rates. The opening pressure set at the factory is witnessed and certified by the TÜV and an individual TÜV certificate is supplied. |
The ULTRAVENT family is designed for a wide range of industrial gas applications, making the smallest pressure ranges manageable and reliably protecting sensitive processes and systems. The valves can even be used in high temperature applications. |
Emerson has announced its Fisher™ GX Bolted Bonnet Globe Valve and actuator system, designed specifically for controlling the flow of critical process fluids in applications in the downstream oil and gas, chemical and petrochemical industries. The actuator can be serviced or replaced without exposing the valve internals or process media to |
the atmosphere, improving safety and reducing downtime. Standard bonnets are designed so that the bolts securing the actuator yoke also hold the bonnet in place on top of the valve. Therefore, the actuator cannot be replaced or serviced without removing the bonnet and exposing the valve internals. Actuator repairs can be difficult in critical fluid applications as a result. The Fisher GX Bolted Bonnet control valve addresses these difficulties associated with critical fluid applications by using a separate, high-strength locknut to secure the actuator’ s yoke to the bonnet. This allows service technicians to easily remove and maintain the actuator while keeping the bonnet in place. |
WIVO VALVES has unveiled its groundbreaking AI-powered smart valves, setting a new standard for industrial safety and efficiency. This innovative technology integrates realtime monitoring, predictive maintenance and automated control to prevent leaks, reduce downtime and optimise energy consumption. Traditional valves rely on manual inspections and periodic maintenance, which can lead to unexpected failures. WIVO VALVES’ new SmartFlow AI System uses embedded sensors and machine learning to detect pressure anomalies, corrosion and wear before they escalate into critical issues. |
Key features include: Predictive maintenance: AI algorithms analyse data to forecast potential failures, reducing unplanned shutdowns; Remote control & IoT integration: Operators can adjust settings via cloudbased platforms, enhancing operational flexibility; and energy optimisation: Smart valves dynamically regulate flow to minimise waste, supporting sustainability goals. |
