SPF Series Super Low Diaphragm Pressure Regulator

The Simtech SPF Series Super Low Diaphragm Pressure Regulator  features a compact molded or machined thermoplastic valve body especially designed to be used in critical low pressure 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.  Both types are self-draining to prevent contamination and bacteria growth and feature a one piece Teflon diaphragm and piston combination.
