The WITT SV805 SMART safety valve combines the proven reliability of our spring-loaded, direct-acting valves with state-of-the-art high-tech sensor technology and electronics. This valve is not just a mechanical safeguard; it is an active component in your digital process monitoring system. The SV805 SMART effectively protects vessels, pipelines and plant components from overpressure by controlled venting of gases and vapours. But it does more than that: Real-time feedback – Integrated electronics record the valve status immediately and precisely.Visual display – Light-emitting diodes (LEDs) directly on the valve visualise the status (open/closed) on site – for quick checking.Seamless transmission – The status signal is transmitted electronically and in real time to your control centre or control system. Highlights: 100% DGRL compliance: meets the highest level of the Pressure Equipment Directive (2014/68/EU), Category IV, Modules B and DTÜV-tested precision: preset, individual opening pressure with official TÜV certificationMaximum robustness: available in either durable stainless steel or brassMedia-optimised: selection of sealing material perfectly suited to the respective gas type or according to customer requirementsEasy integration: small size allows for easy and space-saving installationImmediate visual signal: Red/green diode for direct, intuitive display of valve status (‘open’/‘closed’)Digital real-time connection: transmits status as NPN/PNP signal for seamless integration into your central control centre (Industry 4.0-compatible)   If you have any special requirements or requests, please contact us – we will be glad to help!
