General Purpose
Providing 2- and 3-way functions and available in miniature and subminiature sizes, Gems general purpose solenoid valves deliver Flow
Coefficients (Cv) of .018 to .880. Select from NPT port, manifold or barbed
connection types. Body materials include brass, stainless steel, acetal,
aluminum, and polypropylene. Versions within this group will control
operating pressure differentials up to 1000 psi (70 bar).

design to isolate the media from the
internal components. Diaphragm materials
include Viton®, EPR, nitrile (NSF/FDA),
perfluoroelastomer and EPDM. Numerous
port configurations, voltage options, and
coil constructions enable Gems Isolation
valves to easily integrate into any complex or
demanding system.
These miniature 2-way valves can be configured
for liquid nitrogen, liquid carbon dioxide and other
extreme temperature media. Teflon® coated
plungers, 316 stainless steel guide tubes and
plunger springs, encapsulated coils, and Teflon® or
Rulon™ seat seals produce a truly robust cryogenic
valve for applications requiring high cycle life in
extreme environments.

Solid-State
Intrinsically Safe Relays and Controls
Render any non-voltage-producing sensor, switch or conductivity electrode intrinsically safe
with these relays and barriers from Gems. They amplify sensor load-handling capabilities
in a wide range of AC and DC control switching applications. They are designed for easy
installation in standard circuit boxes in non-hazardous areas. The amount of energy they send
to sensors and switches within hazardous areas is insufficient to cause ignition of a specific
hazardous atmospheric mixture in its most ignitible concentration.
In addition to safety, they offer great
economy by reducing your need for
costly explosion-proof sensors, switches,
controls and housings. Solid-state reliability
assures consistent performance, and with a
completely encapsulated construction they
are impervious to dust, moisture or foreign
material. Select from a broad choice of SafePak® and Warrick models.
