1 Component-tested s DN 6 Safety valves serve to blow out non-poisonous and non flammable gases into the atmosphere in order to protect pressure tanks against overpressure. Please note: Only s that have been set and sealed by us can be delivered with the component symbols, it is thus absolutely necessary to indicate the setting pressure in bar. As functional test, s may be aerated by the way of pulling the hauloff bolt. Repairs may only be carried out by the manufacturer. 4,5-7,0 7,0-10, ,0-13,0 13,0-18,0 18,0-24,0 4,5-7,0 7,0-10,0 G 3 / ,0-13,0 13,0-18,0 18,0-24, Connection thread, G 3 /8 Operating temperature -10 C up to +150 C Setting range 4,5 up to 24 bar (5 steps) Closing pressure difference < 10 % Material brass Seal FKM (viton) Locking torque (valve installation) 13 Nm Important: The supply connection to the should not be < DN 6, the pressure drop in the supply connection not > 3 %.

2 Component-tested s DN 8 Safety valves serve to blow out non-poisonous and non-flammable gases into the atmosphere in order to protect pressure tanks against overpressure. Please note: Only s that have been set and sealed with lead (plumbed) by us can be delivered with the component symbols, it is thus absolutely necessary to indicate the setting pressure in bar. To test their proper functioning, s can be relieved by turning the knurled (thumb) screw to the left. The bearing surfaces and conical seals can be cleaned of impurities by unscrewing the entire upper part - without changing the pressure setting.

4 Component-tested high-performance s G 1 G 2 Safety valve with a very high blow-off capacity will be used for protection of pressure vessels and pressure systems for air and other neutral, non-toxic and non-combustible gases. The valves only can be supplied with a preset pressure, the desired set pressure must be specified with the order. After setting, the valves are labeled and sealed. For functional testing, the can be opened by turning the knurled screw. The bearing surfaces and seals can be cleaned from impurities by unscrewing the upper part without changing the pressure setting. Repairs may only be executed by the manufacturer Safety valves D / G This spring-loaded with a very high blow-off capacity will be used for protection of pressure vessels and pressure systems for air and other neutral, nontoxic and non-combustible gases.
