Controls which are connected downstream of a gas pressure regulator are secured against excess gas pressure. If the required operating conditions are not met, the gas supply is shut off. A safety shut-off valve is required in accordance with EN 746-2 for all gas pressure control systems in which the controls downstream of the gas pressure regulator are not resistant to the supply pressure.
- For positive pressure with over-pressure shut-off
- DN 25, DN 40: with under-pressure shut-off
- Large adjusting range for trip pressure
- DN 25, DN 40: no purge line required
- EC type-tested and certified
