Valve 50 - 100 For positive pressure with over-pressure shut-off


Product Description


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.

The trip pressure is set using the setpoint spring in the measuring unit. The measures the pressure down stream of the gas pressure regulator via an external impulse line. The closes once the set trip pressure has been reached. The valve disc is pressed onto the valve seat and thus shuts off the gas supply safely. The device can simply be manually reset. The pressure in the impulse line must be distinctly below the trip pressure. To begin with, a pressure equalization is carried out via the integrated venting valve in the valve disc using the supplied reset lever. Afterwards, the valve disc is fully opened and finally engages. A breather line must be connected to the measuring unit to ensure that the closing function is activated as soon as the trip pressure is exceeded. A visual position indicator to show the current position of the device can be implemented by means of an electric switch as an option. The free-flow valve design allows for a very large flow rate despite a compact design.
