The
Quartz is available in explosion proof (QX), nonincendive and intrinsically
safe (QN) and general purpose (QG) versions. The robust epoxy coated
anodized aluminum construction makes this platform extremely durable and
well suited for use in corrosive, heavy wash down environments. A broad
range of switching, position transmitter and communication options may be
selected to accommodate most applications.
This versatile platform
adapts to a wide variety of valve systems. Attach the Quartz to quarter-turn
actuators,manual operators, linear operators and positioners using readily
available stainless steel mounting systems.

Enclosures Optimized for Environment
|
 |
QX:
Explosion-proof, water tight and corrosion-proof enclosure is
approved for use in div.1/zone 1 hazardous areas. |
|
 |
QN:
Nonincendive is approved for all div.2/zone 2 hazardous environments
with proximity sensors using a clear cover. Intrinsically safe Namur
sensors or passive switches are available for div.1/zone 0
applications. |
|
 |
QG:
General purpose
features a clear Lexan cover with mechanical switches. All
enclosures are rated NEMA 4, 4x, and 6. |

Rapid
Enclosure Access
Screw-on cover allows
quick enclosure access, saving you valuable maintenance and set-up time.
The cover provides a vapor tight seal and allows entry to internal
components in less than five seconds.
- Faster Wiring
Pre-wired and labeled terminal strip enables quick, convenient
attachment of field wires.
- Wide Variety of
Switching & Communication
Switching options include dual module sensors and communication, Maxx-Guard
proximity switches and mechanical switches. Continuous signal output is
available in a 4 to 20 mA position transmitter.
- Quick Set Cams are Easy to Adjust
Touch and Tune switch settings allow you to make adjustments in seconds
without the use of tools.
- Dual Shaft O-ring Seals Eliminate
Corrosion
Top inner and bottom outer shaft o-rings seal the drive bushing from
both external corrosives and internal contaminants that enter the
enclosure.
- Special drive bushing assures long cycle life
The oil impregnated bronze bushing maintains smooth operation and
eliminates the potential for shaft seizure due to actuator shaft
eccentricity.
- Space Saving Visual Indication
Visual indicator offers excellent viewability without sacrificing
accessibility or adding to space requirements. Indicators are also
available with continuous percentage or three-way indication.

Eliminate Seal Fittings in Division 1
and 2 Areas
FMus ratings certify the Quartz QX series with proximity switches
for use without seal fittings in all hazardous areas. By passing
special pressure piling tests, the all aluminum enclosure was
certified for this elite distinction. Now, a time-consuming
procedure can be safely eliminated in division 1 and division 2
areas.
Consolidate Your Components and Minimize
CostsThe Quartz design offers up to three conduit entries
with extra wire terminations. By terminating solenoid valves in the
switch enclosure, significant savings are realized by eliminating a
junction box, wiring, conduit materials and labor.
