Plast-O-Matic Series PRH / PRHM Pressure Regulators 1/4″ – 3″

• Converts varying inlet pressure up to 150 PSI, to a stabilized, lower pre-set downstream pressure.
• Protects sensitive downstream tools, 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.
• PVC and CPVC models certified to NSF/ANSI 61 and NSF/ANSI 372.
