Pressure regulators

The 700 Semiconductor Series pressure regulator is precision-machined from low-sulphur 316L stainless steel VAR and delivers ultrahigh-purity, high-pressure, low-hazard gases - such as halocarbons, carrier gases, and cylinder purge gases - free of contributing contamination and particulates. The 710 Series pressure regulator includes a poppet directly connected to the diaphragm to ensure positive shutoff, and is well suited to handling higher-hazard gases such as chlorine, ammonia, hydrogen chloride, and arsine.
