Veriflo ABP1SV12BP4PMTP Back Pressure Regulator

The Veriflo ABP1SV12BP4PMTP is a precision back pressure regulator engineered to maintain a stable upstream pressure in gas and fluid handling systems. Featuring 1/4-inch NPT ports and a 0–25 PSIG control range, it provides precise, repeatable regulation essential for instrumentation and high-purity gas services. Built for corrosion resistance and cleanability, the unit has a stainless steel body (ABP1 series) paired with a Hastelloy C-22 diaphragm and a PTFE seat, with a female NPT connection for straightforward integration into existing lines. This regulator is designed for instrument-grade applications and high-purity gas networks, including analytical instrumentation, semiconductor processing, and laboratory gas delivery systems, as well as calibration equipment, specialty gas panels, chemical processing, and industrial process control where reliable upstream or back pressure regulation is required. Common replacements include Veriflo ABP1ST12BP4PMTP, Veriflo ABP1SV22BP4PMTP, and Veriflo ABP1SV13BP4PMTP.
