Quartz explosionproof on/off valve monitor
The Quartz discrete valve monitor is available in explosionproof (QX), nonincendive and intrinsically safe (QN) and general purpose (QG) versions. The robust epoxy coated aluminum enclosure is extremely durable and well suited for use in corrosive, heavy wash-down environments. A broad range of switches, position transmitters and communication options are available to accommodate most applications.
Features
- Wide variety of switching & communication options including solid state proximity and mechanical switches as well as communication and 4-20mA continuous outputs.
- Enclosures optimized for tough process environments
- Rapid enclosure access
- Quick set cams
- Extremely compact with space saving visual indication
- Dual shaft o-ring seals
- The oil impregnated bronze bushing maintains smooth operation and eliminates the potential for shaft seizure due to actuator shaft eccentricity.
- Top inner and bottom outer shaft o-rings seal the drive bushing from both external corrosives and internal contaminants
