Plast-O-Matic PRH Series thermoplastic pressure regulators are ideal for precise control of fluid pressure by maintaining optimal pressure levels to safeguard equipment and enhance system efficiency. They are used in the chemical processing, water treatment, pharmaceuticals and semiconductor manufacturing industries. These Plast-O-Matic PRH Series regulators allow adjusting downstream pressure within a range of 10 to 125 PSI according to specific requirements. They have a frictionless rolling diaphragm, ensuring superior sensitivity to pressure changes, enabling precise and accurate pressure regulation. These Plast-O-Matic PRH Series pressure regulators are equipped with double U-cups that prevent leakage along the shaft and eliminate the possibility of fluctuations in pressure, promoting stable and controlled pressure regulation.
