Quartz QN Series Valve Position Monitor

Brand: Valmet
Add Product to My Catalog

The Quartz is available in explosionproof (QX), nonincendive, intrinsically safe (QN), and general-purpose (QG) versions.

The robust epoxy-coated anodized aluminum construction, and optional stainless steel version, makes this platform extremely durable and well suited for use in corrosive, heavy washdown environments.

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.
Features
  • Rapid enclosure access Screw-on cover allows quick enclosure access, saving you valuable maintenance and set-up time. The cover provides a vaportight 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.
  • 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.
