Quartz QX/QN/QG Series On/Off Valve Controller
Brand: Metso
The Quartz is available in explosionproof (QX), non-incendive, 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 wellsuited for use in corrosive, heavy washdown environments.
Features- Enclosures optimized for environment
- Rapid enclosure access
- Faster wiring
- Wide variety of switching & communication
- Quick set cams are easy to adjust
- Dual shaft o-ring seals eliminate corrosion
