Explosionproof valve monitoring

The Quartz is available in explosionproof (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.

QX: Explosion-proof, water tight and corrosion-resistant enclosure is approved for use in div.1/zone 1 hazardous areas. Available options include stainless steel and epoxy-coated anodized aluminum.

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.

QC: Explosion-proof, water tight and rated for low temps ( -55C ) Enclosure is approved for use in div.1/zone 1 hazardous areas. Available options include stainless steel and epoxy-coated anodized aluminum.

QG: General purpose features a clear Lexan cover with mechanical switches. All enclosures are rated NEMA 4, 4x, and 6.


1. Enclosures optimized for environment Available in three enclosure styles suitable for use in various process environment areas.

2. 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.

3. Faster wiring Pre-wired and labeled terminal strip enables quick, convenient attachment of field wires.

4. 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.

5. Quick set cams are easy to adjust Touch and tune switch settings allow you to make adjustments in seconds without the use of tools.

6. 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.

7. 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.

8. Space saving visual indication Visual indicator offers excellent view ability without sacrificing accessibility or adding to space requirements. Indicators are also available with continuous percentage or three-way indication.
