Orifice flow restrictor Sinterflo® P

Restrictive Flow Products (RFP) are Restrictive Flow Orifices with a single opening or Sintered Metal Flow Restrictors with hundreds of small, micron sized passageways. These are flow limiting devices used to prevent an uncontrolled flow of High Purity Semiconductor Process Gases. Flow limiting devices are installed in compressed gas supply systems or in gas distribution manifolds to control a high gas flow spike. Unintentional high gas flow may be caused by the rupture of a gas supply line, a malfunctioning valve or the failure of a pressure regulator. Our Sinterflo® Sintered Metal Flow Restrictors are highly reliable, low cost, flow control parts that will provide a quick return on investment for a range of applications. These can be manufactured from 316L Stainless Steel, Nickel, Hastelloy® C22, Hastelloy® C276 and other temperature and corrosion resistant materials. Semiconductor Industry, Building and Fire Code Compliance RFP’s can assist in complying with SEMI S5-0310 Safety Guidelines for Sizing and Identifying Flow Limiting Devices for Gas Cylinder Valves, NFPA 318 Standard for Protection of Semiconductor Fabrication Facilities, CGA G-13 Storage and Handling of Silane and other gas safety standards.
