Staflux 185

Staflux 185 is a direct-operated gas pressure regulator controlled by a diaphragm and contrasting regulated counter pressure action.

This device is particularly suitable for high-pressure transmission systems and for medium pressure natural gas distribution networks. It can be used with previously filtered non-corrosive gases.

According to the European Standard EN 334, it is classified as Fail Open.
