Dival 507-512

Direct-operated gas pressure regulator controlled by a diaphragm and contrasting regulated spring action, Dival 507-512 is suitable for use with previously filtered gaseous fluids.

Its use is strongly recommended in medium and low pressure natural gas distribution networks.

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

Dival 507-512 is Hydrogen Ready for NG-H₂ blending.
