The R-K SPF (Super Low Diaphragm Pressure Regulator) features a compact molded and/ or machined thermoplastic valve especially designed to be used in critical low pressure and/or high purity fluid regulating applications. Adjustable screw (Type 1) makes it easy to convert varying upstream pressure into accurate pre-set downstream pressure. Type 2 (1:1 ratio) uses air pressure to control the regulating process. Downstream pressure will be equal to applied air pressure. No metal or elastomer contact with the fluid. One piece of TEFLON diaphragm and piston combination. Self-draining to prevent contamination and bacteria growth. Direct acting full flow and top entry for easy maintenance and minimum water hammer. Available in Flare, Butt fusion, or NPT ends. Ideal for most harsh chemicals, DI water, Bio-Medical, Pharmaceutical and other ultra-pure applications. Type 1 : spring operated pressure regulator
