(other gases on request) Characteristics • Horizontal or vertical installation Type of model / Options (see page 9) • lack epoxy resin coating B • NPT connection thread • Biogas & coke oven gas version (max. 0.1% H2S)

Technical data Type Max. allowable pressure PS 3 bar Nominal width Material Housing / actuator housing/ Die-cast aluminum Temperature range, Class 2 (operating/ambient temperature) Ex protection The mechanical parts of the device do not have any potential ignition sources of their own and therefore do not fall within the scope of ATEX 95 (94/9/EC). Electrical components fitted to the device comply with the ATEX requirements. Preferred installation position For all nominal widths, the direction of flow is indicated by an arrow on the housing. Overhead installation position only after consultation...

Application, characteristics, technical data Structure and function The spring-loaded safety relief valve SL 5 is used for reducing short-term pressure surges upstream of gas consumption systems or preventing an inadmissibly high pressure increase due to escaping gas, and is intended to protect downstream system components from excessive pressure levels. The safety relief valve is composed of the actuator housing and the “control device” functional unit. In the closed position, the gas flows into the actuator housing in the direction of the arrow. There the inlet pressure acts on the underside...
