Quartz QX Series Valve Position Monitor
Brand: Valmet
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.
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.
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.
