Converts varying inlet pressure to a stabilized, lower pre-set downstream pressure.

Large surface area of its frictionless rolling diaphragm provides exceptional sensitivity.

Free movement of the diaphragm on a balanced shaft assures smooth, accurate performance and reliable sealing for millions of cycles.

Double U-cups prevent leakage along the shaft and eliminates the possibility of "creep".

Designed for higher flow capacities and less system pressure loss.
