Brass Single-Stage Regulator Model SSD BRASS REGULATORS
Models SSD, SSE
General Purpose, Single-Stage Regulators

General purpose single-stage regulators are designed for use in noncorrosive gas service. They are recommended for general laboratory use where inlet pressure does not vary greatly (such as liquefied gases) and where high purity is not a consideration.

Brass Single-Stage Regulator Model SSD with Flowmeter

Standard Features

Filter in Seat Assembly traps foreign matter, extends regulator life and reduces maintenance.
Neoprene Diaphragm permits accurate delivery pressure settings.
Outlet metering valve provides flow control.

Optional Features

Relief Valve protects regulator components from the effects of overpressurization.
