Orifice flow restrictor GasPro™

Porvair GasPro™ Flow Restrictors are designed with hundreds of small, interconnected pore passageways which offer significant benefits when compared to single bore restrictive flow orifices. Flow limiting devices are often installed in compressed gas supply lines and gas distribution manifolds to prevent unintentional high gas flow caused by a ruptured gas line, malfunctioning valve or pressure regulator. Applications Gas distribution panels - Porvair GasPro™ Flow Restrictors protect components and offer a possible replacement for needle valves and MFCs in constant pressure and flow applications. Exhaust venting systems - Flow Restrictors can reduce exhaust system requirements and offer significant cost reduction. Flow splitting, flow balancing, dilution and mixing - Flow Restrictors can be custom made for each gas supply line. Controlled venting flow rate during vacuum chamber venting or purging. Pressure snubbers - For the prevention of pressure surges and pressure shock. Flame arrestors - Flow Restrictors can also be designed to create a barrier to quench a flame and prevent the flame from igniting a combustible gas.
