Advanced Specialty Gas Equipment Brass Two-Stage Regulator Model LABE

Brass Two-Stage Regulator Model LABE BRASS REGULATORS
Models LABE
High Purity, Two-Stage, Chrom-Plated Regulators

These metal diaphragm two-stage regulators are specially designed for laboratory applications requiring both high reliability and diffusion resistance. Recommended for high purity non-corrosive gases or gas mixtures, they provide constant outlet pressure regardless of changes in cylinder (inlet) pressure.

Standard Features

Stainless Steel Diaphragms minimize diffusion of air into regulator and eliminate “off gassing” associated with elastomeric diaphragms, thus maintaining gas purity.
High Purity Regulator Design permits vacuum purging of regulator.
Diaphragm Seal Outlet Valve maintains gas purity.
Two-Stage Regulator Design ensures constant delivery pressure over varying inlet pressures.
Chrome-Plated Surfaces provide polished appearance and ease of cleaning.
Cartridge (Encapsulated) Seat Assemblies provide for ease of maintenance and repair.
Filter in Each Seat Assembly traps foreign matter, extends regulator life and reduces maintenance.

Optional Features

Relief Valve protects regulator components from the effects of overpressurization.
