Higher Flow Capacities with Less Pressure Loss

Product Announcement from Plast-O-Matic Valves, Inc.

Higher Flow Capacities with Less Pressure Loss-Image


Thermoplastic Pressure Regulators

Permits Downstream Pressure Settings From 5 to 125 PSI
Designed for Higher Flow Capacities with Less System Pressure Loss

Superior Features:
• Converts varying inlet pressure up to 150 PSI, to a stabilized, lower pre-set downstream pressure.
• Protects sensitive downstream instruments, tubing and filters against damage from overpressure/pressure surges; permits the entire system to operate safely and effectively.
• Downstream pressure settings adjustable from 5 to 125 PSI.
• 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”.
• Optional gauge ports to assist with setting and monitoring pressure.
• For corrosive and ultra-pure liquid applications.
• Sizes: 3/4" and 1". For other sizes, see Catalogs PRH and PRHM.
