2010 Regulators

High Purity Economical Regulator

Dual Stage Forged Brass Low Delivery
Pressure Regulator, Four-Port Configuration,
Neoprene Diaphragms
The PRS2010 Series regulators are intended for primary
pressure control of non-corrosive, high purity, non-liquified gases.
It is recommended for applications requiring consistent, very low
delivery pressure, from a high pressure source.

Typical Applications
■ Gas supply purging Note: Not for use in hydrogen,
■ Purging systems methane, and helium. Seals and
diaphragms are not sufficient to
■ Delivery pressures below 5 psig prevent leakage and permeation
■ Low pressure blanketing of the above gases.
■ Laboratory point of use
control
■ Low delivery pressure with
high pressure cylinders
