PLAST-O-MATIC PRHU High Purity Pressure Regulators

Descriptions of PLAST-O-MATIC PRHU

• Plast-O-Matic Series PRH-U Pressure Regulators are designed to handle corrosive and ultra-pure liquids with inlet pressures up to 150 PSI at 75°F.
• Standard downstream set pressure range is 10 to 125 PSI.
• The normally-open regulators incorporate a poppet seat at the valve orifice to prevent sticking and affecting the sensing of the downstream line pressure.
• Also, one piece body construction and dual U-cup shaft seals help to eliminate internal leakage that could cause the set pressure to creep beyond a safe limit.
• A unique, large-surface, rolling diaphragm seal isolates the spring chamber from downstream pressure sensing liquid.
• This unique design, in conjunction with a pressure balanced shaft, assures smooth performance and stable control.
• CAUTION: Avoid quick closing valve downstream of a regulator to eliminate “water hammer” shock that can cause breakage.

Technical specifications of PLAST-O-MATIC PRHU

•  Machined body constructed of Kynar 740 PVDF , metal-ion free EPDM
•  Fused spigots standard
•  Proprietary Plast-O-Matic pre-assembly cleaning procedure
•  8 hour cold/8 hour hot DI rinse
•  Final Class 100 clean and double bag procedure
•  Maximum flow with minimal drop-off from set pressure
•  New non-rising, smooth-flow stem design
•  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 10 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”.
