Original Press Release:
Model DV22 Mini Diaphragm Valve
Automated Lab Analyzers
Continuous Emissions Monitoring
VICI’s Microvolume Diaphragm Valve is designed for trouble-free use in applications requiring minimal maintenance and maximum lifetime, making it the ideal choice for the process industry, automated lab analyzers, and continuous-monitoring environmental analyses. Three configurations are available: a 4 port internal loop sample injector; a 6 port external loop sampling/switching valve; and the industry’s first 10 port multifunctional diaphragm valve.
Lifetime for the DV22 can exceed 1,000,000 cycles at ambient temperature/300 psi or 500,000 cycles at 175°C/300 psi. The standard valve is for applications in which the sample is above ambient pressure, but it can also be used with sub-ambient pressures, such as when the sample is pulled through the valve by vacuum.
Actuator air (40-50 psi) is supplied to a side port with 10-32 female threads, permitting use of a variety of compression or barbed fittings. A 3-way solenoid is required for actuation, which may be ordered separately.
Maintenance procedures are greatly simplified, since the valve is held together by a single screw and locating pins insure proper alignment.
