Chemical Resistant Pressure Regulation Valves



Plast-O-Matic Pressure Regulators

In PVC, Polypropylene, PTFE and PVDF

PLAST-O-MATIC Pressure Regulation Valves are designed to handle corrosive an ultra-pure liquids with inlet pressures up to 150 PSI at 75OF. The standard downstream set pressure range is 5 to 50 PSI; however with special springs it can reach 75 PSI.

The design incorporates a poppet seat at the valve orifice to prevent sticking and double U-cup seals on the internal shaft to prevent inlet pressure from affecting the sensing of the downstream line pressure. Also, the one piece body construction eliminates internal leakage that could cause the set pressure to creep beyond a safe limit.

unique rolling diaphragm seal isolates the spring chamber from the downstream pressure sensing liquid. This unique design in conjunction with a pressure balanced shaft assures smooth and stable control
