1-1/2" Pressure Reducing Valve PVC

Plast-O-Matic PRH pressure regulators are built to handle corrosive and ultra-pure liquids. These normally-open regulators feature a poppet seat at the valve orifice, which prevents sticking and doesn’t effect the sensing of downstream line pressure. The U-cup shaft seal helps eliminate internal leakage that could cause the set pressure to creep beyond a safe limit. This unique design, in conjunction with a pressure balanced shaft, ensures smooth performance and stable control. Use with inlet pressures up to 150 psi at 75°F. Standard downstream set pressure range is 10 to 125 psi.
