Pressure Regulator Plast.O-Matic Valves Inc. Cedar Grove, N.J.
The new Series PRE pressure regu- lator features higher flow capacities achieved with lower pressure drop. These compact but rugged regulators are designed to handle corrosive and ultrapure liquids and reliably convert inlet pressures up to 150 psi at 75°F to a predetermined maximum down- stream pressure within a set pressure range of 10 to 125 psi. A unique fea- ture is the rolling diaphragm seal, which isolates the spring chamber from the downstream pressure sensing liquid and in conjuction with a pres- sure balanced reinforeced shaft, as- sures sensitive, smooth, accurate per- formance.
