33-7 - Safety self-operated excess pressure valve

The Type 33-7 self-operated pressure-reducing regulator is a bigger size regulator (DN65-DN250) designed to work in all general industrial applications. Excess pressure valve is desinged for opening when the upstream pressure (p1) rises over adjusted value.

This valve is self-operated in that the upstream pressure being controlled is tapped upstream of the valve and transmitted via a control line to the operating diaphragm where it is converted into a positioning force.
