| ASCO
is the worldwide leader in the design and manufacture of quality
of two, three and four way ASCO solenoid valves as well as
ASCO Next Generation valves, ASCO Steam Valves, ASCO Combustion
Valves, ASCO Posiflow Valves, ASCO Switches and ASCO Sensors. |

| These
ASCO switches incorporate a diaphragm-piston type pressure
sensor or vapor-filled temperature sensor transducer
with a fully adjustable electrical switch unit. The
modules are mix 'n match, and can be field or factory
assembled into more than 20,000 pressure or temperature
switch variations right off the shelf. Pressure ranges
are from vacuum to 8,000 psig (560 bar); temperature
ranges are from -30° F (-22° C) to 640° F (338° C).

| H
Series and J Series Pressure Switches |
These
low cost, miniature pressure switches deliver
big performances in small packages. The factory-set
J Series is sealed with specially compounded epoxy
that maintains sealing integrity in harsh environments.
They're vibration resistant up to 10 Gs. H Series
switches have field adjustable set points and
fixed deadbands. Their low cost makes them ideal
for OEM applications. Available open frame or
with general purpose, watertight or explosionproof
enclosures. |
| P
Series Compact Pressure & Temperature Switches |
These
compact switches are most popular with original
equipment manufacturers. They feature ASCO's patented
alternating fulcrum balance plate to control the
operation of one or more electrical snap action
switches. Fixed or adjustable deadband. They are
available open frame or enclosed in epoxy painted,
zinc-coated steel or stainless steel. The design
allows for purchasing of complete two-piece constructions
or separate switch and transducer units. UL and
NEMA approved. |
| S
Series Industrial Pressure & Temperature Switches |
These
rugged switches are designed for tough industrial
applications. The general purpose and watertight
units have aluminum, die cast bodies with formed
aluminum covers to protect the electrical connections.
The explosionproof enclosures have die cast aluminum
bodies and covers. |
| |
|
|
These switches are available in a variety of constructions.
The design allows for purchasing of complete two-piece
constructions or separate switch and transducer units.
Pressure switches are available for combustion service
with UL and FM approval.
