WITT Smart Safety Valve

Brand introduces intelligent gas technology

WITT Smart Safety Valve
The new SV805 Smart can be used for all technical gases.

Gas tech specialist WITT has recently introduced a new safety valve for gases which features integrated sensor technology and an innovative communication interface. For the user, this innovation means more transparency and ultimately greater safety when handling gases, says WITT.

Safety valves are indispensable in gas applications for protecting people, equipment and process integrity from overpressure. WITT’s safety valves are spring-loaded and direct acting. They automatically release overpressure from vessels, pipelines and equipment before an accident occurs. If the pressure drops below the danger threshold, they close again automatically.

The status of the valve is continuously monitored by integrated sensors and communicated via optical and digital signals. Witt has accommodated the smart function extremely compactly in a box which is firmly connected to the fitting. If the valve opens, this is indicated immediately, optically by a red/green diode directly on the valve and digitally by an NPN/PNP Open Collector signal.

The user can be notified every time there is a demand on the valve and is thus informed of process deviations. This transparency enables early intervention and significantly increases the safety level of the plant.

The new SV805 Smart can be used for all technical gases and is available in brass or stainless steel. The opening pressure is individually adjustable from 0.5 to 45 bar (10 - 653 psi). A TÜV certificate confirming the correctly adjusted opening pressure is supplied by the manufacturer. The permissible temperature range is -30 °C to +60 °C (-22°F - 140°F). The component is mounted in any position. SV805 Smart conforms to the Pressure Equipment Directive 2014/68/EU, category III, module B and D.
