Mô tả


Dival 600 is one of the direct-operated gas pressure regulators controlled by a diaphragm and contrasting regulated spring action by Pietro Fiorentini.

Mainly used for medium and low pressure natural gas distribution networks, it ca be used with previously filtered gaseous fluids.

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

Dival 600 is Hydrogen Ready for NG-H2 blending.
