Advanced Specialty Gas Equipment Two-Stage Brass Regulator Model TSD

Brass Two-Stage Regulator Model TSD BRASS REGULATORS
Model TSD
General Purpose, Two-Stage Regulators

General purpose two-stage regulators are designed for use with noncorrosive gases or gas mixtures. They are recommended for general laboratory use where high purity is not a consideration, and where constant delivery pressure is desired.

Standard Features Brass Two-Stage Regulator Model TSD with Flowmeter

Two-Stage Regulator Design ensures constant delivery pressure over varying inlet pressures.
Filter in Each Seat Assembly traps foreign matter, extends regulator life
and reduces maintenance.
Neoprene Diaphragm in Second Stage permits accurate delivery
pressure settings.
Outlet metering valve provides flow control.

Optional Features

Relief Valve protects regulator components from the effects of overpressurization.
