33-7 - Safty self-operated regulator type

The Type 33-7 self-operated universal pressure-reducing regulator is a bigger size regulator (DN65-DN250) designed to work in all general industrial applications. A pressure reducing valve is used for controlling the upstream pressure (p1) to an adjusted set point. A pressure reducing regulator valve is designed to close when the upstream pressure rises above a set 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.
